Yeah, I think that pretty well covers the issues.

Okay, so what I'm hearing and thinking is that we should at drop lirc_atiusb 
from consideration for inclusion, and instead extend ati_remote{,2} as/if 
necessary to be able to let the lirc daemon use it via the provided input 
device, so people can get the best of both worlds (it behaves like a keyboard 
if so configured, talks to lircd if so configured).
