Disable onboard video on Dell 4700 (Intel 915G)
 

I have a Dell 4700 that I've added a GeForce PCX 5750 card to. The onboard video is a Intel Corp. 915G. When I try to play 3D games in Linux using Cedega 4.3.1, the computer reboots itself. The video drivers are installed, latest nvidia version, and glxgears and the Cedega system tests run fine. I called Dell tech support and they had be try to disable the onboard video in my BIOS. However, my BIOS only has an option of "Auto" or "Onboard", no disable factor. They then told me to go into the Windows Device Manager and disable the onboard video card in the profile. However, not having Windows on the system, I can't do that. Does anyone have any experience with this problem and possible solutions? See my lsmod and lspci output below.

Thanks.
