Matrox FB console driver

Matrox FB console driver

[Andy Carlson]

I was playing around with a program that I was using to time differences
between kernels (a silly prime program that puts out 1000000 primes).  I
noticed a very strange behaviour.  On a fresh boot, with the Penguin
pictures that the Matrox FB driver puts up, the prime program runs
1 minute, 30 seconds.  If I reset, it still runs 1M30S.  If I start X,
and exit, it runs 48 seconds.  Is this a known behaviour?  Thanks.

is there any change in /proc/mtrr before and after X?

Good luck,
