I had similar problems with GeForce 8400M. GPU temperature could get up
to 100C in X, which increased CPU temperature in its turn.  I use
powerd, and had lockups with *_cx_lowest settings. I run amd64, i386 was
just fine on the same notebook. 

I've managed to fix it by installing amd64 drivers by nvidia (still
beta and not in ports, afaik).
