Description of problem:
The last month I bought a new graphicscard for my computer.
It's a model Geforce 8400GS from Nvidia Corp.
The problem is when I want to use this hardware I can't.
The problem comes when the kernel (18.104.22.168-12.fc8 and olders) tries to map
the pci i/o memory.
PCI: Cannot allocate resource region 8 of bridge 0000:00:03.0
PCI: Cannot allocate resource region 8 of bridge 0000:00:03.1
PCI: Cannot allocate resource region 8 of bridge 0000:00:03.2
PCI: Cannot allocate resource region 8 of bridge 0000:00:03.3
PCI: Cannot allocate resource region 0 of device 0000:00:00.0
PCI: Cannot allocate resource region 3 of device 0000:02:00.0

I attach more information of my system.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Start the system
I can to use X whith the generic driver nv, but nvidia driver doesn't access
to the hardware.
I hope that my hardware works fine.
See the attachment.

You can try adding:
to the kernel boot options.
The adapter wants a big chunk of contiguous memory and can't get it.
I solved this issue.
The problem was the bios of the motherboard, it was buggy.
I upgraded the bios to the newest.
Now the iomemory maps are diferent and in the lspci -v "Memory at <ignored>"
Thanks for yuor help!
