I can confirm the Asus M3A78-EM works nicely with OS. I've been running this since ~200811 with an AM2 proc, 4x 2GB DDR2 ECC DIMMs and a combination of onboard SATA and an AOC-USASLP-L8i.
The onboard SATA controller (5x ports +1 eSATA) works in both IDE and SATA mode (although I recall some issues in SATA mode on earlier builds). The NIC is detected and supports jumbo frames. No issues with onboard video. Haven't tested power management, but it shuts down gracefully if I press the power button.
