nopes, this didn't help too, machine freezed again after using for 30
minutes or so
all it was doing is playing amarok, fetching sources from svn repos,
and using firefox

lets assume if this is h/w problem, then how can other OSes overcome
this ? is there a way to make FreeBSD ignore this as well, let it
result in reasonable performance penalty.
