This is a nit, but the only version of SunOS with a pageable kernel was a
386i version of SunOS 4.0.  I'm not sure if it was ever released, or if it
was just experimental.  SunOS on Motorola and SPARC processors does not,
and probably never will, page any part of the kernel text.

Of course, as the kernel text and locked down kernel data gets larger, you
will see more paging and swapping of user processes.
