I have tried the attached patch on a clean 2.6.31 source and it is working.

dmesg is showing the following:

libata version 3.00 loaded.
ahci 0000:00:12.0: version 3.0
ahci 0000:00:12.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
ahci 0000:00:12.0: ASUS M2A-VM: BIOS too old, forcing 32bit DMA, update BIOS
ahci 0000:00:12.0: controller can't do 64bit DMA, forcing 32bit
ahci 0000:00:12.0: AHCI 0001.0100 32 slots 4 ports 3 Gbps 0xf impl SATA mode
ahci 0000:00:12.0: flags: ncq sntf ilck pm led clo pmp pio slum part

Will try it later on the latest git, I think the dmesg should identify 
the Board correct then and.

Thanks,
Holger
