Actually, while the Linux compat code is largely machine-independent,
you do need some machine-specific emulation additions to make it work
on another port than the i386. This includes, for example, some
signal handling stuff, etc. This hasn't yet been done for the pmax/mips
architecture in NetBSD. I've never looked into it, but it should not
be much work. Unless the system call numbers are different, which
is the case for Linux/alpha..
