Ok, this sounds like the right short-term solution.

Arguably the right solution, since the extra indirections will probably
be significant cost-wise in terms of execution speed and code size. Or,
continuing the increasing order of complexity:
3. write a native code generator back-end for HP-PA.

There's a comment at the beginning of ghc/driver/mangler/ghc-asm.prl
which seems to relate to this. You might want to take a look.
Cheers,
