No argument there.  If you want to add a feature flag I can start setting it in
my firmware.

But, the if-combinations crap is a bigger problem than that anyway.  I have
some later patches to re-work it to make it dynamically created instead of static,
but that is a fairly big change and I figured I had a better chance of getting
smaller changes upstream first.

Thanks,
Ben
