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.
