Dear Chaz -
  Need to do a little research on this one, it is possible for an FPU to be
hooked into the LC via the PDS.  In fact, we are encouraging people to examine
putting a socket for FPUs on to their PDS cards.
  I don't know if the PMMU can work in the same fashion - will have to see
what lines you get via the PDS connector, but it might be possible to hook 
in a PMMU also.
