I've been meaning to try this for a while.

Today I finally got around to applying it.  The patch didn't apply
cleanly (nothing serious), and also had a couple problems compiling once
I did apply it.

I've appended my cleanup patch.  One of the rs6000-tdep.c hunks is just
a temporary workaround for unrelated build breakage.

I put all this on a local git branch.  I can push it to the archer
repository if you, or anybody, wants to see it there.

I still haven't actually tried it, but I hope to do so soon.
