Not until now, I just ran a test with the 2nd and 3rd heads running X
and the first head (all PCI) sitting at a text VT.  Problem is, the text
VT got throroughly hozed once the X servers started up, incapable of
scrolling when e.g. trying to log in, and getting interleaved in weird
patterns when trying to switch VTs.  I may try putting a Matrox G400 AGP
card in to see if I can avoid this kind of corruption by having a
totally different engine on the 1st head.

However, there is nothing on the console now that the machine has
crashed.  AFAIK there were no events such as DPMS wakeup etc to trigger
the crash.

Now I'm going to see if a) I have or have to go buy a null modem cable,
and b) whether kgdb can give me anything useful.
