Perhaps it is a direct hardware controlled function that only operates 
once the cpu is running in protected mode {ring 3}, or acpi/dmi function 
that operates once the kernel loads drivers for such.

If the second is the case you could try kernel parameters to disable 
acpi (for a giggle).

There might be direct control available from the /proc file system ?

By the way, what manu/model is it ?
