[PATCH] Proper detection of G400 DH MAX cards in matroxfb

Hey,

A simple little patch on matroxfb_base.{c/h} in the 2.4.8 kernel. 
The current matroxfb driver doesn't detect G400 MAX Dual-Head cards 
properly, instead calling them "Unknown G400" and setting their DAC
speed to 300 MHz instead of the correct 360 MHz. This patch fixes 
that.
