I thought Dustin was actually working on moving the ACPI table scanning
into a standalone service based on what currently is in the SMP
sources, which makes perfect sense. I put it there only because it was
the sole user of it that the time, but now that can and should be
changed. As for always using APICs I wouldn't see why not to use them,
apart from that there seem to be some problems with some devices. But
those need to be addressed sooner or later anyway I think. Passing HPET
infos from the bootloader through kernel args is fine too I guess.
