Actually, that's not even true because of our space register usage.  IIRC the
syscall page is at SR7 / 0xc000 0000 (SR7 may be written to in PL 0 only) so
there is nothing preventing us from setting the space register to something
different from 0x0000 0000 and managing a TLB entry for it - nothing but lazi-
ness, that is.
