    Ok, this is probably a long shot, but try:

    setpci -s 00:00.0 67.b=11
    setpci -s 00:00.0 68.b=4f
    setpci -s 00:00.0 6d.b=47
    setpci -s 00:00.0 9a.b=0a
    setpci -s 00:00.0 9b.b=1d

    after a cold boot, and then see if that changes the behaviour. My
    suspicion is that Windows enables some northbridge features that affect
    the behaviour of the system in suspend. Working out /what/ would be much
    easier with datasheets, but ATI and VIA don't seem willing to provide
    them (if anyone could provide me with northbridge PCI configuration
    register specs for any non-Intel chipsets, that would be astonishingly
    helpful)
