The rest of this idea I like, but the statement above seems like the
wrong thing to do. The right thing to do is to preserve a uniform
interface, breaking compatibility. This is a change being made in an
unreleased major version -- an interface change that requires a
recompile is perfectly okay.

I think my followup suggestion of hiding the interface difference behind typedefs is best (keeps the interface as uniform as possible at the source level; and non-PAE will continue to work even without recompilation).
