I booted with a Dell USB keyboard plugged in, as there's no scroll lock or
pg up/pg down keys to let me scroll back.  No serial port, either... 
There's a few different behaviors:

- If I boot with ACPI off, and don't touch anything on the attached USB
keyboard, it has the same behavior as before - stops on that livelock
message.  The USB keyboard is powered at that point - the num lock or
scroll lock lights will light up.

- If I boot with ACPI off, and start hitting the scroll lock key or
anything else during boot to see what happens, I get the runaway db>
prompt as the original poster described.  The keyboard will not light up
for any of the lock buttons.

- Booting with ACPI on, it stops with:

intr 11 at 40001/40000 hz, livelocked limit engaged!
intr 10 at 12342/20000 hz, livelock removed

Booting with ACPI on and with that Dell keyboard attached, I see it
loading up fwohci0 and firewire0 - no uhci messages as before, and it
pauses at

ata0: <ATA channel 0> on atapci0
intr 10 at 2205/20000 hz, livelock removed

and then after a while (perhaps because I left it alone while typing this)
it continues booting.  There's a lot of the 'intr 10' livelock
engaged/removed messages - probably 1-2 per second.

Anyway, since I can see dmesg.boot, here's what says IRQ 10:

pcib1: <PCI to PCI bridge (vendor=8086 device=27a1)> irq 10 at device 1.0
on pci0
pci1: <ATI model 71c5 graphics accelerator> at 0.0 irq 10
pci0: <unknown card> (vendor=0x8086, dev=0x27a3) at 7.0 irq 10
pcib3: <PCI to PCI bridge (vendor=8086 device 27d2)> irq 10 at device 28.1
on pci0
uhci3: <UHCI (generic) USB controller> port 0x4040-0x405f irq 10 at device
29.3 on pci0

I haven't rebooted yet to see if I can repeat this semi-successful boot.
