UPDATE: Sorry, it looks like it was my fault, revision 51 failed to install 2.6.35 kernel and you tried 3.2. Try revision 52, please.
P.S. 2.6.35-1-n900 uImage is 1.7 MiB and stock kernel is 3.6 MiB as you can see on the photo.
pali, I've added it to the boot.scr, it should work.
But if it's not working for anyone let me know ASAP.
n900_, If you are using just U-Boot shell try typing

Did you reused NOLO atags?

Code:
setenv atagaddr ${init_atagaddr}
run sdboot

Okay, these things probably contain modules. Did you update this too?

Wait, n900_, it looks like it's my fault, try revision 50 or 52 (I will update it in a minute)

. Ubuntu is thumb2 compiled, ain't? That missing errata workaround explains constant application crashing.

EDIT:
both kernels are thumb-compiled(CONFIG_ARM_THUMB=y), that is enough to hit the errata
