The fact that backupmenu can't backup kernels, is well known - maybe it should be highlighted in backupmenu's readme, or some wiki, to avoid "trap" for new users. Anyway, it's off-topic here, as it doesn't have anything to do with thumb.
Thanks for your question about thumb programs without cssu-thumb (and freeman's answer) - now I understand more about it, I had no idea about never libs being *mandatory* for new toolchain-compiled programs (as opposed to being optional, giving better performance).

Here's a scenario - Lets assume I have:
- *CSSU Stable*.
- KP52 - we know this has workarounds for an errata.
- Firefox/Fennec (special build for Thumb, linked in required manner).
In above situation, libstdc++ & friends are all non-Thumb versions.
Would Firefox/Fennec still run?
All above is really just for better understandingIt's coz from reading, your post #1 says we only need following:
1. fix in kernel; &
2. (apps or libs linked in required manner.)
I still intend to create a fresh image with CSSU Thumb, repartition my device, reinstall all my apps one by one, etc.

Saw some previous posts claiming that backupmenu completely doesn't work & bricks the device.
I suspect some are not aware that there is another distant & somewhat related problem:
- Start off with KP51.
- Backup in full using Backupmenu.
- Upgrade to KP52.
- Restore using last backup.
Above would unlikely work if my reasoning is correct:
- Start off with KP51.
- Backup in full using Backupmenu.
. - Kernel in dedicated NAND partition is KP51.
. - /lib/modules/current points to KP51 modules.
. - Note: Can't backup kernel in dedicated NAND partition.- Upgrade to KP52.
. - Kernel in dedicated NAND partition is now KP52.
. - /lib/modules/current points to KP52 modules.- Restore using last backup.
. - Note: Restore can't restore kernel to dedicated NAND partition.
. - Kernel in dedicated NAND partition is still KP52.
. - /lib/modules/current points to KP51 modules as per backup.
. - KP52 modules are non-existent anywhere (as per backup).
Above results in a "bricked" device as kernel modules can't be found.
I probably had this several counts & had a couple of useless backups as a result. As a result, am much more careful with backups especially when using KP.

my problem now is that my current state is with kp52 after many upgrades i did to the device (my own - not with apt-get) because i didn't know about the kp52 issue. i am not doing any apt-get updates any more because if something bricks i wont be able to restore. is there a way to overcome this from current kp52 state? i don't wanna wait for the momemt i'll have to go back to a 2 month old backup cause that's goona be a pain...

The case I mentioned mentioned KP, & similarity is that CSSU thumb uses a custom kernel or KP (& where incorrect use of Backupmenu would've triggered the issue).
@impeham: Post to the Backupmenu thread or maybe the KP thread, or send me a private message & I may be able to provide some suggestions based on what I know.

I've got CSSU Stable (lacks many features from CSSU Testing), & many black magic placed on my device. Also introduced a weird defect due to all the black magic. I don't quite have the confidence that a direct upgrade will work that well; besides, I wanna get rid of that defect.
Understanding your stuff here potentially helps me avoid pitfalls when using my black magics in my N900

I've successfully installed the stable version and I really like it.
Could you provide some kind of guide, how to compile packages for that architecture? I'd really like to compile chromium (yes, it's huge).
And if there is a guide, please link it in the first post, so everyone can find it
Thanks a lot!
EDIT: I've had the build environment running, but compiling chromium doesn't seem useful. It's hard to get all the dependencies (you'd need to build some of them too afaik) and also it's said to be slow on the n900 anyway, so forget it
