Not loading 'mga' video driver for Matrox video card

Binary package hint: xserver-xorg-driver-mga

I download the feisty herd 5 desktop CD, when I booted off the CD it came up in only a 800x600 screen.

I have included the output of 'lspci' and 'dmidecode' because I was asked to by someone on the 'ubuntu-devel' irc channel, and I also included part of the xorg.conf file.

I can get other info and install this to a spare partition if needed.
