That's a good start. Together with your memtest results, it
suggests that your hardware is OK.

However,
even when copying the /boot directory from the CD to my machine, it
still produces the same kernel panic, even when starting in safe
mode.

Can you confirm that you have either deleted or renamed /boot before
replacing it with files from the CD. An out-of-sync module does sound
the most likely problem. If that doesn't help, please start DDB and
get a backtrace.

I've run a memtest, and it checked out fine.

Note that memtest cannot prove that your system doesn't have a
problem. There are far too many states that your system could
potentially be in. DRAM is especially susceptable to pattern-
dependent and temporal glitches.

There must be something in my user space or world that it barfs on. I
guess I will try a clean install and rebuild at some point...

If you're not sure where this is being triggered, you could try
adding 'rc_debug="YES"' to your rc.conf (or even a 'set -x' if
you are getting really desperate). This will make the boot sequence
far more verbose.
