This is the state of my v2 tree with Asus M2A-VM support. The patch is against the AMD DBM690T, so you have to compile the amd/dbm690t target for your Asus M2A-VM.
Notes: - If you want a working NIC, revert the part enabling MMCONFIG in LinuxBIOSv2-asus_m2a-vm/src/boot/hardwaremain.c. - If you want a working NIC and ACPI support for SATA, go to LinuxBIOSv2-asus_m2a-vm/src/mainboard/amd/dbm690t/acpi/dsdt.asl and enable the SB5 EVIL HACK and comment out the active "OperationRegion(SB5..." instead. - Thermal setup is wrong. - More than 2 GB RAM will not work (SATA will hang). - FILO will usually work. Sometimes, you may have to poke the reset button first.
Suggestions: - Revert the MMCONFIG stuff. Ignore ACPI for SATA.
