Another point on the Intel part, SMM and SMI handlers are also used with
Intels vBIOS (VGA Bios) to handle built in drivers for LVDS screens and
tv-out chips (they call these modules VBTs and FlexAIMs). I have been doing
alot of research in this lately, and it would be great to impliment this
into coreboot. That's my 2 cents worth.
