I'm trying.
I called dumpsys at the ddb prompt and the kernel seemed to dump but during
the following boot I got nothing in /var/crash.

I didn't. Here's the sysctl list:

# sysctl -a | grep mpsafe
net.inet.tcp.mpsafe_thread: 1
net.inet.udp.mpsafe_thread: 1
net.netisr.mpsafe_thread: 1

The only difference with an out of the box 2.3.1 is the kernel: 
I started from GENERIC, enabled SMP (without APIC), disabled I486_CPU and
I586_CPU, and disabled most unneeded drivers.
