I see something similar, but it may not be related at all.
This is a "no name" latop, Pentium M 1.6, 512 MB ram, running
fedora-development. 

It freezes randomly, however, usually not when I use it, but most often
when it is simply idling at night.
The symptoms however are the same that you see, where everything hangs,
and a hard reset it the only solution.

I have thought it has been a problem with cooling or some other hardware
error, but it could ofcourse be something else, in which case I'd love
to be able to debug some more.
