Hi Henrique!

I've experienced critical temp shutdowns on my X60, model 1706-GMG, BIOS
7BETD5WW (2.16).  The first I've in my /var/log/syslog dating Mar 31st
and was on a Debian sid-amd64, kernel:

  2.6.25-rc7-amd64 (Debian 2.6.25~rc7-1~experimental.1~snapshot.10974)
  (waldi@debian.org) (gcc version 4.1.3 20070718 (prerelease) (Debian
  4.1.2-14+1)) #1 SMP Thu Mar 27 07:59:01 UTC 2008

Since then, I had 18 more shutdowns caused by critical temperature, with
different kernels, up to the latest 2.6.26 (still Debian kernels, not
upstream ones).

I've now a test case which shutdowns my X60: it's a `darcs pull` process
which hangs and then the temperature raises until 128=C2=B0C, so the laptop
shutdowns.

If anyone has any specific suggestion, starting from next Wednesday, Aug
6th, I can perform tests on a clean Debian sid-amd64 (if needed, I can
install an i386) and with vanilla kernels.

Thx, bye,
Gismo / Luca
