AGP mem resource is 64 bits, so no X ?

Hi...
I have a box with a SuperMicro P4DCE+ mobo.
After an upgrade to the latest bios (v1.3, DC6P6273.zip), the kernel
(2.6.28-rc1-mm1) does not recognize the AGP card (an nvidia GeForce 6600 GT).
The propierary 'nvidia' driver does not load beacuse it says:
agpgart: Detected an Intel i860 Chipset.
agpgart: AGP aperture is 128M @ 0xe8000000
nvidia: module license 'NVIDIA' taints kernel.
NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:
NVRM: BAR1 is 0M @ 0x00000000 (PCI:0001:00.0)
NVRM: The system BIOS may have misconfigured your graphics card.
nvidia: probe of 0000:01:00.0 failed with error -1
NVRM: The NVIDIA probe routine failed for 1 device(s).
NVRM: None of the NVIDIA graphics adapters were initialized!
and the OSS driver 'nv' just gives a bunch of black and white stripes on
the screen.
Googlin a bit I read something about the BIOS asigning a 64 bit address
to the AGP memory. Is really this ?

Any idea ?
Anyone has a previous BIOS ;) to share ?
