Torque wrench?  This is a 2500 with a socketed CPU.  I was hesitent to
mess with it, but at this point I figured it's either dead already or
this might fix it, so I pulled it and reseated it.  Then I yanked the 
frame buffer and hit the power switch and waddya know, I got a beep.
Put the frame buffer back in and it still works.  It took me a little
more fiddling with the breakout box to get the console connection
working both ways but it seems to be working now.  Now I've got to see
if I can get an O/S installed on it.

Not much thankfully.
