That could work.  Right now the Config-lab.lb for each architecture is a
fallback image with compression enabled.  Maybe Config-lab.lb is not the
right name.  Any payload that doesn't use compression will need to use the
Config.lb, and any payload that uses compression should use Config-lab.lb

In some cases the ROM size is larger for the Config-lab.lb as well.

I thought about naming them Config-ROM_SIZE-COMPRESSION.lb:
	Config-1M-lzma.lb or 

But it seemed uglier.

The two attached patches implement the switch, the buildrom patch depends on
the Coreboot patch being applied first to create a revision 3091.  I tested
it by not updating the revision, then manually doing "svn up", applying the
patch to Coreboot, and rebuilding.

There is a lot of cleaning up that could be done in the Config.lb files, but
I only touched the ones that buildrom uses, so I wouldn't break anything

Suggestions are welcome.
