Hi Chris,

What's the current state of this?  It sounds to me like it still
doesn't work out of the box.  Having to blacklist the driver and load
it manually is a completely unacceptable user experience.  If you have
to manually choose acpiphp over pciehp, that is also unacceptable.

So if you're still limping along with hacky workarounds like this, I'd
like to pursue this more and see if we can't figure out a better
solution.
