I gave it a try just in case, but sadly, it appears I am getting a 
genuine crash. It did help on another older machine I'm tinkering with, 
but I'm still stuck here. PC-BSD (installed last night to try) has the 
same problem, so I'll give Ubuntu a try and see that works.

Any pointers here on how to troubleshoot this would be most welcome. I 
can't find anything in logs, and the machine just freezes hard when I 
quit X or press Ctrl-Alt-[1-7].

TIA,
Greg.
