In case you have not figured this out already, and if my memory serves
me right, you should be able to download to main memory the video bios
through the pci bus by reading the "pci expansion rom" format defined in
the pci spec. On recent 2.6.x kernels, I think all you have to do is
read the file /sys/bus/pci/devices/*/rom.
hope this helps,
