Yes. The X server must not do video mode initialization, but call the frame
buffer device instead.

what then is the stuff you initialize in the mach64 accel init stuff ?

Like you say, that's _accel_ _engine_ init stuff, not _graphics_ _engine_ init
stuff. The graphics engine takes care of the video mode (programmed in the
fbdev in the kernel), while the X server has to program the accel engine.

in the case of the permedia 2, the engine is only one long pipeline, so the graphic and
accel engine are the same ?

Are you sure about that?

but better would be to take another approach to my questions, ...

when are the init and renint function called ?

i guess init is the first time the Xserver is launched, and reinit is each time 
you return from some console switch ?

Right.

should we save the previous state and reset it on exiting X or something like that ?
Or will the fbdev driver automatically reinitialize the pm2 when you switch back to console mode ?

The X server may restore the video mode by calling the FBIOPUT_VSCREENINFO
ioctl with the `var' it got on startup.
