When I run 2.6.21-rc5 + Andi's x86 patches + paravirt_ops patches,

and the machine does feel pretty hot. Interestingly, when the
machine reboots, the fan spins up to a noticeably higher speed, so
it seems that maybe something is getting fan speed control wrong.
Well, 128C is more than hot enough to boil water and well above the
thermal tolerances of most CPUs, so I would imagine that were your
CPU actually that hot it wouldn't be capable of printing the
"Critical temperature reached" messages, let alone properly rebooting.
