I fixed the bad flash by using a Beaglebone Black and the OpenWRT screwdriver package (recommended by the coreboot project). Luckily, the board had pins directly to the flash via an SPI interface otherwise I might have had to use a Pomona clip.

Did you have any luck with this? There might be a BIOS setting in the menu that allows you to disable the SMM lock, and as icon suggested on IRC the speed racer exploit might also be a feasible workaround.
Another idea might be to try using coreboot on this board and simply not set the SMM lock bit until you need to do so ;-) There's a decent chance the Bayley Bay CRB implementation will work, though you may need to do some customization for your board: https://review.coreboot.org/cgit/coreboot.git/tree/src/mainboard/intel/bayle...
