Fortunately, that stretch goal is now already funded.

No, it's loaded from a Spansion S25FL128P flash chip on the (quite
simple) ASMB4 board:


(It looks like the board is just a way for ASUS to sell copies of the
BMC firmware separately from the mainboard.)

Yes, the S25FL128P on the BMC board is in a SOIC-16 package, and it's in
flashrom's flashchips struct.  And there's nothing else on the board's
power rail that could cause problems with ISP.  So I see no reason why
flashing with a test clip wouldn't work.
