Hi all,

Intel ICHx have one(?) ugly feature: reboot by TCO timer can be disabled by the hardware. Current message isn't very informative and can cause false bugreports, so the attached micropatch.

BTW this hardware braindamage already reported on Sony Vaio pCG-FX140.

Best regards.

P.S. What's wrong with my previous patches including Intel ICH and SCL90E66 PCI quirks ?
