Ok, here's more info. It DOES seem to be a regression. I spent half a day 
yesterday trying to trace this down, with no success. Multiple bisect 
attempts ended up with non-bootable kernels on the very first iteration. 
Today I just wanted to post all possible logs / configs to Bugzilla and - 
it "suddenly" worked... And the change that made it work was - I disabled 
CONFIG_FB_PM2 in the kernel...

So, I think, this shall be qualified as a regression, although, I have no 
idea where. pm2fb.c itself hasn't (effectively for little endian) changed 
since 2.6.24. To make it visual

v2.6.24		works		works
v2.6.25		works		fails

/me thinks he should trade his ap400 to the Linux Kernel Testers Inc. for 
LOTS of money.
