I mentioned this patch to you way back in April at ELC, but am only now out from under things enough to clean it up and submit it. I've basically cribbed the corresponding code from shpchp_pci.c, so there are no big surprises. If it's still possible, I wouldn't mind this going into 2.6.18, but it wouldn't be the end of the world if it went into 2.6.19.
