Hi!

Is it possible that the deferred IO implementation in kernel 2.6.22 is
buggy?

Yes, that's possible. There was a key bug fixed in 2.6.25. You'll
probably want at least the following commit:

commit        de7c6d15e354bc94a846f03749819768c331280a
fbdev: defio and Metronomefb

Very good, thanks a lot!
Is there an easy way to retrieve that specific patch?

I think git cherry-pick should be possible. Alternatively, I think you
can download just the fb_defio.c changes from:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=de7c6d15e354bc94a846f03749819768c331280a

and apply it that way. Hope that helps.
