More vendor vs. ACPI methods - FAN?

On the same poor old Toshiba Portege 4000:

{pts/1}% cat /proc/acpi/power_resource/PFAN/state

state:                   off
system level:            S0
order:                   0
reference count:         0

{pts/1}% cat /sys/class/thermal/cooling_device0/cur_state 0
{pts/1}% cat /sys/class/thermal/cooling_device1/cur_state 0
{pts/1}% cat /proc/acpi/toshiba/fan

running:                 1
force_on:                0

Looks like we need something similar to video handlink for FAN as well ...

hmmm, do you mean register the toshiba fan as cooling devices?

thanks,
