The board has an IPMI controller which may cause all sorts of screwups.

Greg, Colin, can you get a sharp high-res photo of the region of the
board where the flash chip is located and upload that to imageshack or
some other service? I want to be 100% sure that we're not dealing with a
situation where two flash chips are present, and the IPMI controller
switches between chips to confuse flashrom to no end.

Yes, the flash chip seems to be totally confused. Once we have the
output of the commands above, we have a good chance to find a way to
whack the chip on the head so that it will respond normally again.
