At this point the only way we could get all of the Opteron type boards
to build was to temporarily disable CAR.  The CAR implimentation was
riddled with #IFDEFs and in some cases multiple layers of nested #IFDEFs
that made the code very difficult to manage.  The CAR issue is
definitely something that needs to be discussed at the LinuxBIOS Summit
in October with everyone involved coming to an agreement on how it
should work.  
At the very least, CAR should be tested on all of the affected boards before
commiting them to the repository.  We simply want things to work
reliably.  If you want to enable CAR for a board that has been tested
and is known to work, then it is a local decision.  But by default we
need something that is stable and manageable for everyone.
