There is an /etc/modprobe.d folder, but I've reviewed every file in
there without any luck.  There is a lirc.conf file in there, but every
line is commented out by prefixing with #

I came in tonight, and the red light was continuously on.  dmesg was
just continuously reporting messages.  After a few experiments, I
discovered that the sensor was placed too close to the TV, and appeared
to be getting corrupted by the emissions from the TV.  I moved it on top
of the PC and that problem disappeared.

I removed the second lirc opts line, and now the irw program is
reporting data.

It'd be nice to figure out why the debug mode is on, but hopefully I'll
be able to get the channel changer script working from here.

Many Thanks
