Patched AN35N Bios w/ Linux, C1 Disconnect on:
idle system, 39-41 C
heavy activity, 50-51 C

Though I have since added two additional fans to my system.  When it is under
heavy activity, it will obviously go up to 51 C.  When it is finished and 
becomes idle again, then the CPU temp will quickly go back down to 39-41 C
because the additional fans remove the heat quite effectively.

Ross, you should reply to them and say the problem affects windows as well.  I
can't imagine it immune.  Although, windows is not that aggressive, I think 
it's still affected.  It doesn't matter that people don't think windows has
this hang.  It still has it.  It doesn't matter that they can't reproduce it 
under what they think are normal circumstances.  It _still_ has it.

Actually it isn't a OS problem, it's a BIOS problem.  It has nothing to do with
the OS.  It's the quality of their boards we're talking about.  If only they
get that...
