Memory Type Range Register.  It's there for speeding up graphics card=20
operations.  You can find a lot of info on MTRRs=20
in /usr/src/linux/Documentation/mtrr.txt .  Never ran into problems=20
like this myself, but I don't use anything other than standard VGA=20
since xterm/konsole are much more flexible than the ttys.

=2D-=20
   I find that having a pint or two is a good problem-solving technique.
   Especially if it's vodka rather than beer.
