Well that user level process _is_ the X server. And as people rightly
observe also SVGAlib, the kernel and has rather limited arbitration

Moving some of the low level support doesn't change the stability per se,
but it does give you more control over things and especially over
abitration. The problem is there is a penalty for that. A syscall costs time
and you have to really get the syscall count down to sane levels. A fast
graphics card can plot a line in less time than a syscall takes, so it
is a real hard issue
