Actually, the mips1 (r00) CPUs dont' have bi-endian support, so
this is only an option at *all* for mips3 DECstations -- 5000/50,
500/150, or 5000/260.
Even there, you would still need an cross-endian syscall stub to
byteswap the relevant syscall arguments, and in-kernel emulation of
any SGI-specific syscalls not already in NetBSD's svr4 emulation.

Yup, 'fraid so.
