Hmm, I had misread this diff as being another instance of what Adrian had
found. I think this is actually not correct. The parent of a pci device
('dev' here) is a pciX device. pciX devices do not implement the
PCIB_POWER_FOR_SLEEP method from pcib_if.m, so this probably just broke
Adrian's Asus laptop as now it will always use D3 again and ignore _SxD.
You said that this change fixed your laptop, yes? Did it work before Adrian's
change in r274386 and break afterwards?
