This will not work with unmodified kernel sources; for the modem  you
need  the standard serial driver which cannot coexist with the MPC8xx
serial driver (they use the same major numbers).

We implemented this some time ago; see the linux-2.4  module  on  our
CVS server and search "drivers/char/serial.c" for "MPC8xx_UART".
