Yes, the OS should set it. So we should add an option to lxbios 
lxbios --set-boot-complete or something.

Ok. This makes sense to some extent.

lxbios can back up the cmos for you. So when you call flashrom, you
should also call lxbios to put the cmos values for your bios in place.

It would be nice if flashrom could call lxbios externally to
automatically do that, or to have a wrapper script. 

One of my customers uses 2 small scripts


that flash a fiven bios image and write the according cmos contents to
