LIRC does not rely on a specific major. But to be honest, the last time I  
looked into this issue, was when devfs was bleeding-edge...

So, we need some advice here how to proceed. Should we try to register an  
official major number for LIRC? Should we try to have a minor number  
mapping, e.g.
/dev/lirc/serial/0 LIRC device on 1st UART serial port
...
/dev/lirc/serial/n LIRC device on n-th UART serial port
/dev/lirc/parallel/0 LIRC device on 1st parallel port
...
/dev/lirc/parallel/n LIRC device on n-th parallel port
/dev/lirc/usb/0 1st LIRC USB device
...
