That would introduce regressions for some users, though.

I actually think we should merge acpiphp with pciehp and make one driver that
can use both types of signalling. There would be a problem with getting
notifications for the same event from both sources, but that doesn't seem to
be unsolvable.

And I don't think that that one combined driver should be modular.

Thanks,
