This is something that I've also been looking into for a while; I think
it'd be totally feasable for this to be added to the new NetBSD toolchain
to be included in 1.6.
I have two machines currently running 1.5-current with the new toolchain
and ELF. If these patches can be put cleanly into the m68k tree, we can
make binary snapshots for Amiga and Mac immediately, and start testing.

I will try out your directions on one of these ELF / new toolchain systems
and report my status soon.
