All other problems have also been with the PMC parts IIRC.
Do you have any other LPC flash chips?
I don't think the chip is the problem;
Not the particular chip, but I would like to rule out the chip type.
I just tested another one which I know works fine in the ASUS A8NE-FM/S (however, it's a Pm49FL004 too).
That board has a CK804 southbridge though, right?
The writing fails with that chip.
AFAIK all problems involve MCP55 and PMC flash, even if it's just the inactive chip in a BIOS savior and flashrom should write the other, active chip in a BIOS savior.
Ward's problems are with MCP55+SST-in-BIOS-savior. As I recall Ward got SST chips working if they were put directly in the socket on the board.
The PMC chips can do both LPC and FWH so they have their own state machine which is a bit different from those in a single-protocol chip.
Not a lot, but maybe enough to cause trouble under some circumstances, which happens to collide with what flashrom does.
Yes, it's just a suspicion.
