Sanjeev, want to take care of this?  Machine ID update info is in 

This strategy will unfortunately involve patching bootloaders.  But if the 
default is to use GPT12, it should work out okay.

Hopefully we won't have to do the same thing for the other Beagle-derived 
boards, Devkit8000, Touchbook, etc. etc.  Then again, I suppose this will 
eventually just be another property passed in via DT, with a single 
machine ID.
