I can make it work for HPET if I fix up the point at which the IRQ remapping code registers a notifier on the platform bus. (At IRQ remap setup time is too early; when it registers the PCI bus notifier is too late.)

IOAPIC is harder though as the platform bus doesn't even exist that early. Maybe an early platform bus is possible but it would have to turn out particularly simple to do, or I'd need to find another use case too, to justify it. Will continue to play....

While playing with HPET I noticed I need s/CONFIG_PCI_MSI/CONFIG_IRQ_GENERIC_MSI/ where the variables are declared at the top of msi.c to match the change I made later on. Can post v3 of the series or you can silently fix it up as you go; please advise.
