Oh, the interesting thing I wanted to point out was this:

% grep irq DELL.mptable 
fxp0 <Intel EtherExpress Pro 10/100B Ethernet> rev 2 int a irq 9 on pci0:16
fxp1 <Intel EtherExpress Pro 10/100B Ethernet> rev 2 int a irq 10 on pci0:17

lpt0 at 0x378-0x37f irq 7 on isa
fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa

Note that there are 6 different IRQs used by PCI cards.
(fxp0:9, fxp1:10, fxp2:11, fxp3:14, ahc0,1:5, ahc2:15)

I only actually used fxp0, ahc0, and ahc1, though.
