Disable onboard graphics?

I have a problem. Installing an Nvidia Geforce 4 kinda scrambled my dual boot... XP takes it fine, but Ubuntu entered two instances of my onboard card, different PCI IDs, etc. It's messed up. A Linux junkie told me I may have to completely disable the onboard graphics to fix it. I like having two monitors working at the same time on Windows. However, I may have to disable the onboard graphics to fix my Ubuntu. So, is there any way to completely disable it?

My BIOS has two options:
A "Onboard" (self explanatory)
and
B "Auto" (looks for a card on PCI so I'm told)

But, both operating systems can still see the onboard. Is there any way to completely disable it?
If there is, and I have to use it, I'd like to be able to use Ubuntu, and if I need Windows, just re-enable it and reboot.

Any help is greatly appreciated.

Well, you didn't mention what model of computer you own; but likely the answer is no -- you cannot disable the onboard video controller completely -- at least not from my experiences with my Dimension 3000.  My 3000 had the same options (onboard/auto) and the only way I could get around not being persistently bothered by Windows at bootup that it had found new hardware was to go into the device manager and select disable for that device.
