I've been using the input-layer ir-kbd-i2c driver for my bt878-based
hauppauge card for several months now (since 2.6.0-testsomething), and
it works alright for me. Since 2.6.something (2.6.2 I think) this driver
is included in the vanilla kernel sources and compiled automatically
once you select bttv-support.

The driver generates events via the /dev/input/eventX interface, and
these can be processed by lircd with lirc's input-layer support.

I had to generate a new lircd.conf in order to get it to work, but other
than that everything was pretty much straight forward. The whole process
is documented by several mails by me and others here in the list's archives.

I can't provide you with further info on how the code works internally
as I don't have any programming experience, you'd probably be best off
if you contact Gerd Knorr directly if you've got any technical questions.

Regards,
Stefan
