By the way - I have not run my tests on a G3 system.

All the relevant builds were done on a G4 running NetBSD 5.2.
The kernels built and tested were left up for
subsequent builds - FWIW.

I did some early builds on a NetBSD 6.0.1 Intel system (VM),
but I quickly abandoned that because builds started failing on earlier source
bases.  I chose to suffer the longer run times of a real PPC build rather than
chase the cross build problem(s) on a not-yet-set-up NetBSD 5.2 system.
