But I'd rather supply a 2-step patch to drop the template macros and use #ifdef'ery inside the macro definition for ppc64/ppc differences, given that long-term we won't need the second version.

Are you sure you need that? Most of the stuff should be generic. Please take a look at Linux's PPC_LL macro for example. The stack layout varies slightly, but that should also be reasonably easy to catch.
