I did not get anywhere trying to change the entry to what you show 
above. For the rawhide edition on this system, it resulted in X not 
starting at all. For the FC4 edition, it did not make the screen active 
either way.

Anyway, there are 6 logs and configs on bug 144597
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=144597

For bug 154408, the last two entries are logs and configs for the FC4 
edition.

The rawhide system seemed to work with or without the BusID specified 
for the Intel "PCI:0:2:0" - The BusID was configured for both FC4 and 
rawhide for the MGA card.

One thing that I could not understand is why the vesa driver did not 
work for the rawhide but the mga driver worked somewhat. The screen was 
active and the mouse seemed to change the scramled mess on the MGA card 
monitor. (800x600 LCD). With the vesa driver, it worked as if you chose 
single head.

The menu button on the LCD monitor showed 640x480 / 60hz / 31.5khz. The 
display should have displayed at 800x600. I hooked another monitor (CRT 
1280x1024) and saw the same garbled mess on the screen. I was checking 
if the display was trying to work at a higher resolution than the cheap 
LCD could manage.

I changed the line to "1280x1024" "1024x768" etc: The monitor display 
fine for the Intel side. The Matrox seems to be stuck in 640x480 but 
with information for 800x600 or something. I get about 5 mouse pointers 
when moving the mouse over the MGA video area.

Thanks for the suggestions.
