You're mostly correct, except some minor clarification required for
the "just yet" part. :) lirc_zilog won't ever be in the lirc
distribution itself, Christoph objects to it, because of its
legally-murky use of a blob extracted from a Windows driver to load
transmit codes into the driver (plus, the code is somewhat fugly in
places...). And the hdpvr driver needs to be patched to enable its IR
part. But once you do that, and grab lirc_zilog from somewhere like my
lirc git tree, yup, it all works[*]. There are reports of instability
w/the IR part enabled, but I've also heard from quite a few people who
haven't had any stability issues at all recently (might have been a
firmware fix?). Will be poking my own hdpvr again RSN...

[*] these should both already be in the latest Fedora 12 and 13
kernels, including recent fixage to properly bind lirc_zilog to the
hdpvr, courtesy of Gavin pointing out my stupidity to me.
