 I recently tried to boot netbsd-5 under bochs, it fails to get any
 disk interrupts because they are enabled on the 8259 between when
 the IOAPIC is initialised and when all the 8259 interrupts are masked
 by (IIRC) ioapic_anable().
 
 In this case the disks are on piixide0@pci0, but it goes through
 pciide_machdep_compat_intr_enable() - which tries to use 8259 interrupts.
 
 I gave up working through the morass of the ide code, 'boot -2'
 to disbale ACPI let it boot - which was enough for the tests I was
 running.
 
 'current' boots fine, dunno what extra changes it has.
