Provided that you were using the current version 3.11 of ROMSPEED, you
can find the sources in the ROMSPEED archive. There is not really much
PMMU-related code except for the modification of the descriptor relevant
for the mapping of the ROM contents (this is what _sysbase points to):

        move.l rombuf,d0          ;new "ROM" address
        or #5,d0                  ;write protect
        move.l _sysbase,a0
        ptestr #2,([8,a0]),#7,a0
        move.l d0,(a0)            ;update descriptor in the existing table

If there is no (working) PMMU support I would expect nothing visible to
happen, indeed. Except for having less RAM because the ROM contents have
been copied.

Take care
