[LinuxBIOS] Fun with LAR....

[Jordan Crouse]

Hey all -

I've been working on modifying buildROM to understand LinuxBIOSv3.  Part
of that effort is being able to add payload and arbitrary blobs of binary
(VSA, VGA BIOSen, etc) to existing LARs.  So, needless to say, I've been
hacking away on LAR over the last few days, and the following patches
are the result of that.  I'll try to explain a little bit more about
each patch as it comes.

Please keep in mind that these are not set in stone - I expect heavy
criticism and thought about whats gong on here, and I know you won't let
me down. :)
