OK, so it is not ITE IT87.

Ah yes. That's a limitation of the DOS port of flashrom.
Usually the SB600 SPI base address is near the top of the address space
(4 GB). On your board it is below 1 MB, and AFAIK Rudolf said that we
can't map any region below 1 MB as uncached due to CWSDPMI/DJGPP
limitations.

If anyone has an idea how to overcome these limitations, we can fix
flashrom for this special case.

Michael? Is there a good way to handle this?
