I've managed to get my Apple wireless keyboard working by compiling the hid-apple kernel module. This is missing from the installed kernel modules and is required for the kernel to recognize the device.
With this loaded, the steps below (hildon-im-xkbtool --list, setxkbmap, etc.) get everything working nicely.
Cheers.

We already know that it is possible to make some bluetooth keyboards work with the N900. At least, Jeff succeeded with a Stowaway IGo.

In order to make an apple bluetooth keyboard work in maemo 5, we would need to fulfill the following requirements:
1, pair the keyboard
2, make sure the keyboard has been registered as an input device (hildon-im-xkbtool --list)
3, Run the setxkbmap command to associate the keyboard layout we want (and not the default SU-W8)
So here are my observations:
The problem with the Apple wireless keyboard is that although it pairs fine, it is not being registered as an input device (hildon-im-xkbtool --list won't show it in its output).
Since maemo 5 uses the bluez stack, we have at our disposal the bluez commands to try to understand what is happening.

Good, found it. Now let's create a connection:
Nokia-N900-42-11:~# hcitool cc 00:1D:4F:A7:71:46
Seems good. As mentioned in many places, the Apple wireless keyboard requires encryption and authentication. So let's do that.
Nokia-N900-42-11:~# hcitool auth 00:1D:4F:A7:71:46
Not connected.
Bummer, indeed.

What could be the problem? Maybe someone experienced with bluez can chime in. Please use this thread to report all the information pertaining the apple wireless keyboard and the N900. With some community effort, we'll find a way to make it work.
Cheers,
Ulysses

Fantastic.
Maybe you could attach the kernel module here as attached file for those who don't have a development environment set up. And could you please mention the commands used to load it?
That would be great.
Thanks in advance.

I think I'm against posting a lone little kernel module in a forum on principle alone.
My intention is to package this up exactly like kernel-module-cifs, Kernel-module-nls-utf8, or kernel-module-ntfs packages, but I'm not sure how fast I'll get to this.
Possibly someone else could get to it sooner?
Cheers.

stuff like this makes me wonder what other interesting hacks people have dreamt up that we'll never know about, unless we stumble upon threads like this!!
.... hmmmmm i wonder??

I would Love to See a solution. and I am not alone see this thread http://talk.maemo.org/showthread.php?t=34872
But I need something that a Regular Joe Non-coder can utilize.

Of course a package would be the best, but failing that, a kernel module compiled against the latest kernel version would be nice too, and pretty much normal practice for linux users.

Hi,
I've set up a development environment in order to compile the apple module for the kernel.
A couple of observations:
In the wiki it is said that for external kernel modules, kernel headers will suffice:
However, this package cannot be found.
So I resorted to compiling the module against the full source. Let's get the source.
Now let's configure the source tree.
Let's grab the latest hid-apple.c and the latest hid-ids.h form the kernel gitweb, adapt the Makefile:
Compiling the module is OK. Now let's put it on the device and do a :
Not good. Let's go back to scratchbox and strip the version info in case the problem stems from a slight version mismatch:
And on the device:
Any advice?
Thanks, Ulysses

Probably getting a version from gitweb is what's borking you. Try following:
http://wiki.maemo.org/Documentation/...Kernel_Modules
The appropriate line will be
http://wiki.maemo.org/Documentation/...Kernel_Modules
The appropriate line will be
# CONFIG_HID_APPLE is not setwhich should be changed to
CONFIG_HID_APPLE=mCheers.

It's already a part of the kernel source. You got the appropriate version when you did
[sbox-MaemoKernel: ~/maemo_kernel ] > apt-get source kernelCheers.
