Yes. I actually did a bunch of work on this front earlier today. Its
completely untested as yet though. Its on my todo list to actually try
it out on real hardware (PVR-250) tonight.

I'd say wait a day or three, I've already got a pretty decent start on
it, and if I'm lucky, it'll Just Work when I test. If not, it shouldn't
be a huge amount of extra work to get it going again...

Current lirc_i2c still works with 2.6.30. If that's still not new
enough, backporting the hdmi bits to 2.6.30 might be simple enough.

I should probably read that, but meh. What I've got already compiles
and looks sane at a glance, I just need to actually test it. :)
