Not exactly. We always wanted to have the option of compiling
support for different drivers from the menu, which is what Jon's
change was about. The difference here is that we don't require
the support library code to be selected to make those options
visible.

Anyway, it sounds like your fine with this approach so let's do
it! I'll send this patch out properly.
