Given the hardware demands on page size, you'll have trouble mapping most
4k executables on 8k hardware. The other way round should be fine.

Historically (read: Sun's strategy) all sparc executables are based on 8k
page sizes, although most models have a 4k (hardware) page size. This is
still the case in the NetBSD sparc port, although we don't even have a
port for an 8k sun4.
