92 well, we'll need to do a little work on the manual scripts to have the fan
93 work and to be sure that the thermal won't reach critical trip point where
94 it would shutdown.
95 i'll take a look and post some scripts that should help. you'll have to be
96 sure that you have installed lm_sensors and cpufrequtils and that you have
97 compiled the cpufreq modules into the kernel or as modules and you'll have
98 them loaded at boot. we'll have to make the processor slow down when the
99 thermal goes too high. also i'd like to know what are the capabilities of
100 your processors:
101 a cat on the /proc/cpuinfo and then on cat /proc/acpi/processor/CPU(x)/info
102 where (x) is the number of the core to know what sort of management it can
103 support. you should have cpu0 and cpu1 if you have a dualcore.
