I have fixed fbdevhw beyond the patch on that page with the help of Geert.
I have hopefully found the bug in the fbdev driver now, please test
http://penguinppc.org/~daenzer/patches/fbdev-fboffset.diff
or
http://penguinppc.org/~daenzer/fbdev_drv.o
which is the 4.1.0 fbdev driver built with the patch applied. If it works,
I'll submit it to Branden and upstream.

Did you mean xserver-xfree86? Either way, I don't think it's useful
(xserver-fbdev is outdated) or necessary (the relevant XFree86 developer (me
;) is aware of the problem).
