My setup is similar to yours, I bought it trying to get easy coreboot support (easy, not immediate, and also some features), I've spent some 6 months trying to "install coreboot" and it still does not boot. But I'm not experienced in low level programming and I don't have that much spare time to experiment. So don't count on me as a volunteer. It's also not something I'd like to do on ssh. You have to do a lot of trying and exchange one chip for another, and it's already slighty tiresome if you're there physically, let alone having to wait for someone on IRC... There's also some risk of breaking something that I wouldn't like to take.

Features I would like:
- Serial Console Redirection
Does your board have a serial port (RS232)? The photos look a lot like my board. Mine has one but I don't see it in yours

Try to see the marking on the EPROM chip. I bet is the small chip on a 300MIL 8-PDIP socket between the red connectors (IDE and SATA ?) follow that thread in case it is the same chip, I finally bought the winbond chips from digikey in June 2010

And have worked perfectly with flashrom for me all these months.
- AMD Athlon II X4 615e support
I have a Phenom II X4 910e Looks quite similar. Yours is revision RB_C3 also, I think?
I found fidvid.c did not suppport this version and coreboot hanged while setting frequency and voltage of the CPU. I've apparently fixed it but I have a 1600 lines patch, and I really should see how to break it up in chunks that can be reasonably reviewed . In fact for fidvid.c itself the patch is bigger than the file. I hope I can do something this weekend to break into decent patches...
My board still doesn't boot though. It currently gets to ram stage and hangs while enabling pci devices. It's similar to a problem I found in romstage and I worked around it with a patch that wasn't probably the right approach (it wasn't commited). This time I'll have to see what's causing it (likely that I have an RX781, not an RS780, it's more or less the same without graphics, but I may have to tweak something somehow).
- ECC Memory support
Not sure this works
- Readout volt,temp,rpm sensors
- Boot 2.6 kernel support
- Grub 2 (lvm, mdadm, ext4) support
I think this will work
I got two M4A78 PRO motherboards that I would like to give new life by getting coreboot on them.
New life ? They are not so old as to have died yet... There're similar boards already that might work: src/mainboard/asus/m4a785-m src/mainboard/asus/m4a78-em
