Geert suggested just moving atyfb.c from 2.3.6 into 2.2.10 - that is
definately less risky. But when Linus says developmental release, it
means this version would never have left the project team in a normal
software company.

67/200 (I think, from memory) but this is a Rage II+ not a Rage Pro (It's
a rev 1 box) so the values may not apply to your situation well.

Hmm... it went away for me. Want the vmlinux? I can send it to you if you
want (not that it should be any different than one you built, but...). It
has pretty much normal config+mac-on-linux patches.
