Oh, yeah, and that :)

I assume you have the LABEL in a new line? i.e. this:

ACTION!="add|change|move", GOTO="mm_serial_end"
DEVPATH=="/devices/pnp0/00:05/tty/ttyS0", ENV{ID_MM_PLATFORM_DRIVER_PROBE}="1"
LABEL="mm_serial_end"

Baudrate? The modem should use 57600bps, as that is what MM expects.
If a different one, you can add a new rule like:
DEVPATH=="/devices/pnp0/00:05/tty/ttyS0", ENV{ID_MM_TTY_BAUDRATE}="115200"

Also, 8N1 as serial port settings, but I doubt it's different in your modem.

BTW; does the PLATFORM_DRIVER_PROBE tag work if you tag
"/devices/pnp0/00:05/" instead of "/devices/pnp0/00:05/tty/ttyS0"?
