Seems I was a little premature in claiming a solution. :( The new
graphics card has massively reduced the frequency of the lockups, but
they are still occurring, and interestingly I got one this morning
while still at the command line (my PC boots to a command prompt),
before I had even started the GUI session. This seems to be even more
evidence that I'm trying to trace a hardware problem rather than
something with Ubuntu, I think I'll try posting on one of the hardware
lists and see whether anybody has any ideas.
