OpenBSD lists the M4000 as supported:

While I didn't actually mention NetBSD here, since it's not the same as OpenBSD,
I checked that as well now and it currently doesn't support Fujitsu CPUs, but
that's work-in-progress, same applies to sun4v, i.e. T1-T5. For sun4v, I'm actually
in contact with the developer doing the work.

Find someone on the sparclinux Linux kernel mailing list willing to do the work
and create a Bountysource campaign to sponsor the work. I assume, you can get
it done for maybe $5000-$10.000.
