I wish! :-)
I don't think anyone knows how many mappings there are. Every single
mips target, for instance, likely has a different mapping. Instead of
trying to second guess all of them, remote.c is being changed so that
the user can specify them at runtime. That way, when (not if :-) the
default mapping screws up, the user can fix it.
enjoy,
Andrew
