On my Toshiba M45-S355 (Toshiba Bios, Pentium M 750 - 0.8 at 1.86GHz, Debian Etch) I see the same using Kernel 2.6.21.6

I never do that, but see below (Kernel 2.6.21.6):
cat /proc/acpi/thermal_zone/TZCL/trip_points critical (S5): 105 C
cat /proc/acpi/thermal_zone/TZCL/polling_frequency polling frequency: 2 seconds
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor ondemand
