Some drivers don't report events but deliver the signal to the lirc 
daemon. The daemon decodes the signal. Decoding of several IR protocols 
and mapping of each possible remote to events are things much easier 
done in userspace.
Aslo LIRC is not only about IR input but also output.

See following mail from Christoph Bertelmus for more details.

This shouldn't be necessary since the lirc daemon can already read from 
input devices.
