in prinzipal that is the way it should be but this is not quite true
as X utilizes user-space (SUID-ROOT) drivers quite a lot - so even though
X is in its on VM it is fiddling with low level resources that are normally
under kernel control (i.e. sti/cli). So this is actually the
same problem in Linux as you noted for QNX.
