I tried to see if this is the case on my SMP board, but I don't seem to
have acpi attached to any interrupt:
[root@nik: ~] ps -axg | grep irq
24 ?? WL 0:00.00 (irq18: mpt0)
25 ?? WL 0:19.30 (irq19: em0 mpt1)
26 ?? WL 0:00.00 (irq16: xl0 uhci1)
27 ?? WL 1:57.07 (irq17: fwohci0 drm0)
28 ?? WL 1:09.27 (irq13: em1 ichsmb0)
29 ?? WL 0:00.02 (irq20: pcm0)
30 ?? WL 0:02.19 (irq2: uhci0 bktr0)
31 ?? WL 0:02.84 (irq14: ata0)
32 ?? WL 0:00.00 (irq15: ata1)
36 ?? WL 0:00.00 (irq6: fdc0)
37 ?? WL 0:00.00 (irq1: atkbd0)
Is this the right way to check for this?
