Default Problem with Dual Head GeForce4 MX 4000 and Intel845G

I'm trying to get X working with 2 video cards - the builtin graphics,
using the i810 driver, and a pci Nvidia GeForce4 MX 4000 using the
Nvidia 6629 driver. When I boot the machine, the BIOS has an option to
select whether the primary graphics should be AGP or PCI. When I set it
to AGP, I can start X on the Intel graphics, but when I try the Nvidia,
the X server crashes. When I set the primary graphics device to PCI, X
will start on the Nvidia card, but I get these errors when I try to
start it on the Intel:

(EE) I810(0): Cannot read V_BIOS
(EE) I810(0): VBE initialization failed.

I've tried running both X servers separately, and together - same
results. I've also tried the NoInt10 option for the i810 driver, but it
still won't start. I think X is always querying the BIOS for
information about the video card, and the BIOS returns info for whatever
card is set as the primary, regardless of which one X is set to use.
Here are the config files I'm using:

X only on i810:
X only on nvidia:
X on both:

Here are the logs from when I try to start the X server:
X on i810, bios set to AGP, works:
X on i810, bios set to PCI, X won't start:
X on nvidia, bios set to AGP, X crashes:
X on nvidia, bios set to PCI, works:

I also tried the vesa driver with the i810, but it says that it can't find a device
matching the device id I put in the config file.

Is there a fix for this? Perhaps an way to tell X to probe the card
directly, rather than going through the bios?
