This board works with 0710 RC2 with the exception of the Onboard LAN.
The installation is not seamless however. You will probably get to a BusyBox Prompt when trying to install. If so you may need to enter BIOS and enable AHCI mode.
Then at the install screen press F6 and type "all_generic_ide" ssimilar to the ASUS P5N7A-VM post: 
You will also need to disable the floppy in BIOS if you don't have one installed.
Anyway - still testing, will update this once I have it all up and running.
