Nice!

That's sad, because we Indigo R3K users on this world are desperately
needing these patches to be able to run NetBSD on our machines. In the
end NetBSD is the last free OS that works on these machines. Not even 
OpenBSD has support for R3K Indigos AFAIK.

Say, which PR refers to the kernel patch(es) (incl. the MAC address fix 
for early Indigo R3K)? It would be cool to be able to build that kernel 
for future NetBSD releases.
