Add support for ASUS F2A85-M board
The patch is based on Thatcher board. So far it boots Linux (3.2/3.7), internal network adapter works, AHCI works. External PCI/PCIe slots works too. Power management/ACPI seems to work. Internal VGA works with dumped ROM (VGA/DVI), but lacks GART. PCI pref devices are being relocated by Linux, reason unknown. This is a good start. USB and XHCI untested but visible.
