OK, that makes the box suspend alright, but neither that nor any other
box or laptop I've got can get out of suspend without locking up.
If I revert just /sys/dev/acpica and /sys/i386/acpica to aug-01 both
suspend and resume works (sortof, it does tend to panic later on).
It starts failing around aug-05 and then detoriates from that on to the
current state of locking up hard on resume.
It also fails in the exact same way on non-ATA systems, so I think I'm
out of the loop this time :)
