After some more compiles, I finally figured it out; it's the RAM. The Hynix HMT151R7BFR4C-H9 sticks I have work fine in Libreboot, but didn't work with any Coreboot release I tried (tagged 4.6, the last build reported in board status for the KCMA-D8, and master). Tossed in the old RAM I had lying around, and Coreboot boots fine even on master.
I wasn't expecting the RAM to be an issue since it worked in Libreboot though. As I understand, RAM compatiblity varies between the stock/proprietary BIOS and Libreboot/Coreboot, but I didn't think the compatibility would also vary between Libreboot and Coreboot.
