GNU/Linux Desktop Survival Guide

As suggested in http://copland.udel.edu/~doke/dell_d810/, you can get the cpu temperature from /proc/acpi/thermal_zone/THM/temperature. When the laptop is at rest, I get about 38C. When it's active, I get around XXC. When it's active, and on my lap (with my legs blocking the air vents on the bottom), it goes up to XXC. The safety auto-shutdown threshold seems to be 95C?
