Great! Email me directly (or CC: me) if/when you'd like some more testing.
Another thing that could be a factor here, is that neither method
(acpiphp or pciehp) seems "automatic". The user has to know to load
one or the other module, or at least manually add them to /etc/modules.
This could account for some reports of the mechanism failing.
Shouldn't one or the other module be loaded automatically somehow
when a system has hotpluggable slots?
Probably a chicken-and-egg issue, I suppose, or something for a distro to fuss over.
Cheers
