I fully agree that using ndisasm is by no means more complicated than
using my fcode detokenizer detok. All x86/efi option rom discussion sounds rather 
like a game of not stepping on the others' toes rather than technologically driven

OpenBIOS can be used on top of a PC BIOS as well, thus it could allow to
use any Open Firmware compliant pci card in a machine that still has
different firmware in rom. This is one step towards the great unification.. 

If the concept of having a diversity of hardware architectures available
is going to survive, there has to be a generic solution to the early
initialization issues.
