Hi Larry,

In general this depends on the drivers available and whether you need 
special functions from LIRC. Not all drivers have been ported to become 
in-kernel but the more popular ones seem to have been ported. To some 
degree this also dictates whether you use devinput or /dev/lirc?. You 
can check your driver to see which it takes.

If you don't need functions such as irexec or irxevent then you don't 
need to use LIRC anymore. I use irexec myself so I can shutdown myth 
from my remote.

I wrote a description of how all this hangs together. It is written in 
the context of LinHES so while most of this holds true, some aspects 
such as initialization files, may not be done the same as in your 
distro. This wiki entry also describes various test points you can use 
to help you debug the messaging as it goes through the layers.

To be honest, I have not been involved nor have I followed most of this 
IR development so this wiki entry is based on what I have determined in 
my own quest to get things working. I just figured I would document it 
for the benefit of others who I saw struggling. If more knowledgeable 
folks have suggestions then feel free to let me know. I suppose I should 
link this into the myth wiki in hind sight.

Hope this helps point you in the right direction.
