I ran sysutils/memtest twice.  Both times, it failed to panic the
system.  I have yet to bring the system down and boot into a "real"
memory/hardware checker, however.  I usually just go with
ultimatebootcd.com when testing, but if you have other suggestions for
tools, I'd welcome your input before we schedule to do the testing.

Thanks!
