Might be.  When I boot this machine under FreeBSD, I do get odd messages
(I think they were in that dmesg) about the SCSI controller's interrupt

Data point:  NetBSD is running in 64-bit mode, SMP, without configuring
ACPI at all.  I assume they just talked to the APIC the old-fashioned way
or something.
