Okay - it doesn't sound like there is much overlap here between qemu
and coreboot.  On coreboot cbfs is used for pulling out option roms,
executables, and floppy images - none of which have much use under
qemu anyway.

So, maybe we should just go back to the discussion of a config
interface.  I think it would be nice to have one api for getting
config items for both qemu and coreboot - something like
get_config_u32("ShowBootMenu").  On coreboot that info could then be
extracted from cbfs and qemu can get in from the "cfg port".

Does that make sense?
