I had a Matrox Millenium G400 and many problems with this card...
I don't remember it system freezes were among them, but what can I say
about them is that they were caused by the buggy kernel mga module
(which doesn't even support all features of the chip, eg. the chip has 3
texturing units but the module gives access only to 2 of them).
And I am 90% sure that it is the module's problem (only 90 because I don't
know if the module wasn't fixed as I've changed the gfx card half a year
ago).
