That did not help. I can boot an SMP kernel in single user mode if that
bit of information is of any value.  While the exact failure point is
not always the same, it is always just before the start of login.  In
other words, sometimes I will see the "Additional TCP options" message
last, other times I will see the "Starting moused" message and get a
pointer drawn on the screen.

I jotted down the following from the kernel messages:

APIC_IO: Testing 8254 interrupt delivery
APIC_IO: Broken MP table detected: 8254 is not connected to IOAPIC #0
intpin 2
APIC_IO: routing 8254 via 8259 and IOAPIC #0 intpin 0
SMP: AP CPU #1 Launched!
