Is it possible to get a Nvidia PCI video card and a Nvidia AGP video card to coexist?

Hello,

I have an Nvidia G-Force 2 MX (PCI) and an Nvidia 7800gs (AGP) (that I
just bought). I can't get both cards to work at the same time. One
device is conflicting with the other. However, when I had my ATI 9800
Radeon Pro I did not have this conflict with the other PCI Nvidia card.
I also noticed that I can get the two cards to work if I reinstall the
OS (Windows XP Pro) but I do get the following stop errors quite a bit:

After the OS (Windows XP Pro) is installed and if I remove one of the
two cards (and the their drivers) I am not able to get the two cards
working together again. However, both cards run just fine independently
(with no stop errors).

After doing some additional research, I found the following thread that
contains a similar problem to what I have:

They mention that Nvidia drivers conflict with each other and that if
you are going to have a PCI and AGP card working together, that they
both can not be nvidia cards.

So, it is it possible to get a Nvidia PCI video card and a Nvidia AGP
video card to coexist peacefully? If so, how is this done?
