Things seem to work a lot better since I moved ath0 to share with
the (idle) ehci0:

$ dmesg | grep 'irq '
aac0: interrupting at ioapic1 pin 0 (irq 11)
wm0: interrupting at ioapic2 pin 5 (irq 3)
aac1: interrupting at ioapic2 pin 0 (irq 11)
uhci0: interrupting at ioapic0 pin 16 (irq 11)
uhci1: interrupting at ioapic0 pin 19 (irq 10)
uhci2: interrupting at ioapic0 pin 18 (irq 6)
ehci0: interrupting at ioapic0 pin 23 (irq 5)
ath0: interrupting at ioapic0 pin 20 (irq 5)
piixide0: primary channel interrupting at ioapic0 pin 14 (irq 14)
piixide1: using ioapic0 pin 18 (irq 6) for native-PCI interrupt
lpt0 at isa0 port 0x378-0x37b irq 7
com0 at isa0 port 0x3f8-0x3ff irq 4: ns16550a, working fifo
pckbc0: using irq 1 for kbd slot

The BIOS would only give me a limited set of choices.  I'm also
going to see if I can find a BIOS update for this box (Dell
PowerEdge 1800).
