No. A long time ago, I wrote the code to support the 3-level MMU
found in the Sun 4/400 series, but it was never put to the test
seriously due to lack of testers who actually own some hardware
to test on..

The NetBSD/sparc distribution kernels do not by default include the
code for 3-level 4/400 MMU. You need to build a kernel using the
kernel configuration option `SUN4_MMU3L'.

If you're interested in making NetBSD work on the 4/400, let me know..
