The problem with this is that in order todo this svgalib leaves the
fd
for /dev/mem open. Which of course is a big nono from a security point
of view.
In fedora that's actually not THAT bad actually; still not too good tho
As for your question; there is a fremap which may do what you want, but
the use of it is a bit tricky sort of so I'm not sure if you really want
to do that.
