So I made a bid of progress... I added the following lines to
/etc/modprobe.d/blacklist:
blacklist agpgart
blacklist intel_agp
And I rebooted. Right now I have that and the BIOS set to "OnBoard" and
I'm trying to see if I can configure additional screen on the Matrox card.
It's not fixed yet but atleast I can boot without crashing.
