What about a permedia2 board then ? Maybe i should write a fbdev for my dual
pm3 board, i wanted to do it anyway. But the current fbdev support in the
glint driver would have to be changed anyway, as the permedia3 is a 128 bit
chip, unlike the permedia2.

huh ?

Anyway, i will be giving it a look this week end.
