Random panics on new hardware

I've been fairly out of touch with FreeBSD stuff for a while so I hope
you'll all excuse me asking a quick question here...

I've made the mistake of upgrading my terribly slow old computer to some
lovely new hardware -- now I get random panics (usually page fault, but
I've had a privileged instruction fault and a couple of pmap errors --
I can't remember them all exactly, since it's probably not a software
issue I haven't paid that much attention).

Most of the hardware is new (Asus A7V8X-X mainboard, AthlonXP 2500+ CPU,
512MB DDR 333 RAM (Crucial)) so I'm not sure where to start looking for
which bit might be faulty.  Memtest86 found no RAM faults.

The case was mega-cheap so it's possibly a PSU issue, but somehow I'd
expect the system to freeze/spontaneously reboot in that case rather
than complete a FreeBSD panic crash dump (until I turned the latter
off cos they take so long with 512MB RAM and a fairly slow old disk).
Although I could be mistaken about that.

Does anyone have any hints about where the problem could lie?  I've
searched around but not come up with much sadly.  I've included the
dmesg if that helps point out any problematic hardware.  If you need any
more info please just ask.
