+ The pmac_zilog driver for the z85C30 chip on many powermacs
+ historically used the device numbers for /dev/ttySn. The
+ 8250 serial port driver also uses these numbers, which means
+ the two drivers being unable to coexist; you could not use
+ both z85C30 and 8250 type ports at the same time.
+
+ If this option is not selected, the pmac_zilog driver will
+ use the device numbers allocated for /dev/ttyPZn. This allows
+ the pmac_zilog and 8250 drivers to co-exist, but may cause
+ existing userspace setups to break. Programs that need to
+ access the built-in serial ports on powermacs will need to
+ be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
+
+ If you enable this option, any z85c30 ports in the system will
+ be registered as ttyS0 onwards as in the past, and you will be
+ unable to use the 8250 module for PCMCIA or other 16C550-style
+ UARTs.
