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.

and it now reports the chip as a "SST unknown SST SPI chip", with all four operations not working. Attached are the output of the failed flash attempt, and a probe from after that attempt.
can you please send the output of "flashrom -VV" and "lspci -vvvnnxxx" to the list, and send me privately the old backup image, the image you tried to write and the file "contentsnow.bin" created by 'flashrom -r contentsnow.bin -f -c SST49LF160C', and also check whether different runs of flashrom create the same contentsnow.bin? It looks like flashrom managed to mess up your chipset configuration that much that most flash accesses do not do what they really should do anymore.
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.
