BIOS, likely. Linux might steer just CPU.

unlikely; missing undocumented/proprietry hook for Linux-ACPI.

BTW, I could reach and check via net an Acer TM382, a PackardBell (NEC) 
E4000, a Gericom *3000, a Toshiba EQUIUM A110: all have /proc/acpi/fan/
clean, KVERs is between 2.6.17.14 and 2.6.19.x.

So, seems the acpi-fan stuff is the worst documented, if reachable at all.
