After lots of cleanups, bugfixes, feature extensions and testing, my diff to add Asus M2A-VM support to coreboot has shrunk almost to zero.
Please look at http://www.coreboot.org/ASUS_M2A-VM for information on the current state of board support.
Thermal setup still uses the dbm690t code and needs to be written.
To build an image for the Asus M2A-VM, simply apply the patch below and build the amd/dbm690t target.
I plan to copy the src/mainboard/amd/dbm690t directory contents to src/mainboard/asus/m2a-vm and apply this patch on top of it.
Working images with video BIOS and FILO are available on request.

If it weren't for the socket difference, I'd be interested to see if the dbm690t would just work with the Asus changes and only have one target.

Why does it matter if you comment out settings for a device that's off? Same question for the pci 3.0 device above.
Thanks, Myles

Right now I ignore the fact that thermal setup is completely wrong. The machine still boots, though. There are other differences as well.
You're right about the striking similarities between targets, though. I'd really like to have one generic RS690/SB600 board and keep the differences well contained in separate files. My cleanups have been focued on that task.

The weird thing is that the board wouldn't boot otherwise. These changes are fairly old, though, so it may be possible that they are no longer needed. It will be a week before I have access to the hardware again.
