not really. The debate is if the only code that uses gx drivers is X. We
seem to go into that direction. (DirectDraw()). And then it's perfectly
ok that X has direct access to the hardware.

[ well, i still maintain that a kernel trap is cheaper than an IPC call,
but if the price would be X in the kernel -> brrr. And if X would be
still a separate process, then we had the IPC AND the kernel trap
overhead -> this is a loss i think ]
