Speedups? Probably not; in fact, you'd probably see _slowdowns_. The
kernel is made to be reasonably fast and compact to reduce the amount of
time spent in kernel tasks (which have varying degress of "exclusive
processor use"). In user processor mode, all those problems are solved.
Since a mmap() (memory mapping) of the video memory is done via 'options
INSECURE' or the apm module, the X server is really as fast as it can get.
