Did you do a 'portsnap extract' as well? Fetching alone isn't enough.

You should definitely use the radeon driver for this hardware.

Saved cores are kept in /var/crash by default. See "dumpdir" in
/etc/defaults/rc.conf. Try

  kgdb /boot/kernel/kernel.symbols /var/crash/vmcore.8

Hmm. Signal 12 is "non-existant system call invoked". That's one I've
never seen before.

It has access to system internals via /dev/mem and /dev/io. So it can
potentially screw things up pretty badly.

It might also be a hardware problem. Testing the RAM would be a good
place to start.
