That part of the patch is correct. Can you give me a Signed-off-by:
line? I will ack and commit. See
http://linuxbios.org/Development_Guidelines#Sign-off_Procedure for details.

Thanks, I now see that it is indeed a problem with the SPI translation.
Can you try to flash some random data to the rom? Verify will fail. Then
try to read back the rom and upload both original random data and
readback result somewhere (rapidshare etc.) and I'll try to find out
what the flash translation chip really supports.

And please tell me how much RAM the machine has (if it is more than 2
GB, I need the amount of Video RAM as well).
