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".
