Are you using default Linus's 2.6.37 kernel or patched kernel from http://gitorious.org/nokia-n900-kernel ?Can you publish your modification/patches (or use gitorious or somethink else...)? In next weekend I'd like see on it
and help you.

Not without changing some of the closed binaries (though MeeGo does have bme, a minimal mce, the SGX drivers, and the modem drivers, so it might be doable if someone has the time to do it.
So which parts from nokia 2.6.28 kernel must be backported to 2.6.37 (which is not in upstream)?

Just a little progress report:
So far I am able to load bios/codecs from latest androids. 720p h264 decoder loads but gives mmu fault, lower resolutions work with no problem, obviously some more work is needed
.
bridgedriver updated to this commit http://dev.omapzoom.org/?p=integrati...c50efd16351f96
Which is kernel version:
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 32
EXTRAVERSION = .7
backporting higher versions needs a little more work, but I will continue to try.
Attached is patch if anyone is interested.
to apply it in scratchbox:
apt-get source kernel-power
cd to debian
replace rx51power_defconfig with one from zip
copy phys_to_page.diff series and dspbridge.diff to debian/patches
build kernel
after installing on n900 you will need to change shm_size for bridgedriver. to do so edit /etc/modprobe.d/bridgedriver and change value from 0x400000 to 0x500000.
original files from /lib/dsp wil most probably not work, you will need newer baseimage.dof . Search internet for it, ti has several free download versions.

I've been digging through mafw's code, and stumbled across this in the changelog:
* Disable native flags in playbin2 temporarily since this is causing
trouble with some videos. Also, allow videos with resolution up to 848x576.
* Changed highest resolution for fremantle
So I'm guessing that limit can be removed, unfortunately, grepping for 848 returns no results, so I'll have to look where it's limited.

This page has some info on attempting to bring a newer kernel to N900 as well:
