I have exactly the same problem.
I have a 2.4Ghz P4, 512MB ram, 32MB AGP Asus GeForce 2 GTS DDR, and a 4MB PCI Matrox Mistique.
the AGP card is the primary display, the matrox is the 2nd.
I have had exactly the same thing happen after upgrading Xfree86 to 4.3.0 from 4.2.0.
Its really annoying the hell out of me. You can get so used to a nice dual head machine :)
Does anyone have a working dual head machine with Xfree86 4.3.0 and 1 or more Matrox cards?
Looking at the Xfree86 log file, the last line i see is also: ------ (II) Truncating PCI BIOS Length to 32768 ------ This happens after/while initialising the PCI Matrox card.
running top, xdm seems to consume all available CPU.
Paul: Please keep me updated if you find a solution. I will do the same.
When i get some time, I might try swapping out the matrox card for an S3 Virge PCI and see if i get the same results.

I have a test box that had been running X 4.2 in a multihead config for a while now (1 Nvidia TNT2 AGP, and 2 Matrox Millennium/Mystique PCI Cards). I upgraded yesterday to 4.3.0 only to find out that any attempts to run X result in a complete console lockup (still have access via ssh). Since the box was running 5.0, I loaded 4.8-RC from scratch this morning only to find the same problem.
Using a 4.2.x standby XF86Config, X works fine when running a single card (either TNT or Matrox). I get console lockups when attempting to run multiple cards.
