Depends on how close to the generic serial driver model the multiface
driver was at that time. To get a rough idea of what might be involved,
compare the Atari SCC drivers of 2.2.x with the current 2.4.30 one.
>From a quick glance, the struct m68k_serialswitch has to be replaced by a
struct real_driver. rs_receive_char is replaced by adding the char to a
flip buffer, and calling tty_flip_buffer_push(tty). m68k_register_serial
is replaced by tty_register_driver, and the generic serial driver info
needs to be filled in. Should not be too complicated.
