Great, thanks!

Probably yes. The laptop.org GIT tree only has 2 revisions. Such an
amount of change could easily be handled with subversion and
coreboot.org surely could handle that. The final decision is made by
Stefan, though.

It would certainly make outside contributions easier.

I'm pretty sure AMD is interested, although those people working on
Geode targets for coreboot will want to test as well. The ability to
tailor the VSA to do exactly the things we need and skip the rest is a
really exciting prospect.

Please do.
