Fedora 6, Dell Optiplex GX260 and PCI Video

I hit Fedoraforum.org with this but got nothing. It has been driving me nuts. I searched the net high and low but I cannot put my finger on what the problem is.

I have a Dell Optiplex GX260 which I use with Fedora. It currently runs an updated 'Fedora Core release 6 (Zod)'. I want to run multihead on it.

When I run with the onboard video adapter (part of the Intel 845G), everything works okay. As soon as I try to use my PCI Matrox G2+/QUAD-PL (Quad G200 32MB PCI), the kernel will not even unpack, or it crashes with a weird EIP error and khelper message right after it tries to load.

I looked at the obvious like trying to disable the onboard video but the BIOS has two modes: Onboard or Auto, in auto mode, the onboard video is disabled as soon as a second card is sensed in the PCI slot.

A lot of people always mention driver configs and Xorg.conf and such but this seems way before all that. It's not like the machine comes up but X is unavailable, the kernel crashes and you have to hit the power button.

The setup works fine on other OSs like Windows XP. But I can't even run the install procedure with Fedora. If leave the PCI card in, the install procedure will crash from the DVD. After I installed correctly and used the onboard video for a while, I decided to reinstall the Matrox to give it a try but I get the same result.

From reading other boards, I notice other users seem to have the same problems with PCI video cards but I don't know why. I've even seen references to similar problems on other flavors of Linux.

If anyone has any idea, please let me know, I'm pulling my hair here. I'm hoping there's a miracle kernel patch or maybe a magical IRQ setup I need to do. Whatever it is I'll give it a try. The Dell has an AGP slot also, do you think an AGP card would give me the same problems?

Thanks.
