Jarod, I appreciate your patience.  I am trying this with the
ir-kbd-i2c module loaded.  I get these errors:

[root at localhost lirc]# ir-keytable -r
Not found device rc0
[root at localhost lirc]# ir-keytable -a /etc/rc_maps.cfg
Not found device rc0


I am obviously still doing something wrong.  I am still getting some
activity in irw for some of the keypresses. but not the ones I had
issues with previously (and all register in dmesg).  I am probably
missing something obvious though.

I changed "type: UNKNOWN" to "type: RC-5" although that line is
commented out anyways, so I would not imagine it makes much of a
difference (# table haupp, type: RC-5).  Do I need to edit my
/etc/rc_maps.cfg?  I have posted it to
http://www.mustbethemoney.mine.nu:8080/rc_map.txt  Maybe something is
missing in that file?

Thanks for the help!
