They're actually Janne's work, not mine, I just patch monkey'd them
into place. :)

Yeah, someone reported that to me last night, was planning to dig into
it this weekend. Finally doing so now...

There are some issues... The current git head lirc_zilog is for 2.6.31,
which includes a bunch of i2c changes. However, even with your patch,
I think there's still some magic missing in lirc_zilog to get it to
register properly to bind to lirc_zilog on 2.6.31... To work on on
pre-2.6.31, I think lirc_zilog needs the i2c changes reverted to
function with earlier kernels, I think. This patch I believe should
do the trick, testing it shortly...
