doesn't work anyhow (due to current and future fundamental differences
between NetBSD and HP-UX device semantics). This can probably be shared
with other m68k ports now.
A fair bit of this, the m68k core dump and exec goo, can probably be
made into a generic m68k hpux module, eventually.
More to be placed in hpux_machdep.c - keep your eyes peeled...
