That shouldn't be a problem.  The arm26 version was basically a
placeholder until I got round to doing proper FPA support, which I haven't
yet.

This might be slightly trickier, but there's no good reason why they need
to be different, I don't think.  It's just likely to need cpu_loswitch(),
or its equivalent on arm32, to be modified to use a common structure.
Come to that, the code should really be shared, but that's likely to be
rather more hassle.
