As little as possible after boot/init.

That means that BIOS is used for APM mode selections
if APM is being used and for ACPI state-switching.
Oh, I guess we have to acknowledge that hidden SMI code
also, but Linux doesn't use it AFAIK, it's just there
and being executed.

Those are all that I know of before being fully awake.
