speaking of that : what is  the simplest/safest solution to allow the use of
direct access to the accel engine with the fb driver ?

in my example, how can I make the use of glide safe with the fb driver on
voodoo 1 ?

how does "normal" fb driver cope with this kind of things , say switching
from the console using the frame buffer to X using "native" access to the
board ?
