Great. Finally some news I can use (besides someone getting M4A785-M
supported which may give me a headstart on mine - M4A785TD-M)

Great. So we have no P2B regression and with a 256MB stick on DIMM0 I
managed to boot into the Slackware install I have been using to test
coreboot, with 256MB recognized as usable.

But. when I tried this patch, I don't know if it's something else,
when I added an 128MB stick in DIMM2 the boot process hung at/after
the vga bios of my ATI Rage 2C (POST shows 0xfe). Also I'm not getting
any serial output. I'm sure I didn't change my Kconfig from before
which has always had serial output enabled.
