the glint fbdev support was developped for apus by michel daenzer, the only
graphic card we have is permedia2 based. So it should work without problem on
ppc. (there is some crash in the current version when starting enlightenment

I don't think the tnt2 stuff is ppc clean, but the mga driver was worked on
ppc by Gerd Knorr i think.

On i386, i got a G400, and downloaded the glx-mga stuff from there, it has a
nice debian package also directly available for potato and slink. But i think
something is bad for it, since i don't managed to have it working. I think i
miss a mesa 3.1 version, or am using a bad Xfree server. 

I didn't have time to look more into it though, ...
