There are multiple channel changing scripts in the mythtv wiki, any
that are for lirc can be adapted to work. There's also one linked to at
another location I'll link to later on in this reply. :)

hardware.conf is a not part of upstream lirc, despite what legions of
Ubuntu users would lead you believe. It doesn't exist on most other
distributions outside of Debian derivatives. All it does is feed params
to your lirc initscript though. Fedora uses /etc/sysconfig/lirc to do
similar, not entirely sure about other distros.
Adding a standard lirc daemon config file that lircd itself reads is
on my TODO list, so we *do* have a common centralized config, rather
than every distribution rolling its own.

You're missing the necessary binary blaster index-to-signal-waveform
data blob that has to be loaded into the driver for it to be able to

Read up here:
Start at "Either way, you still need a firmware image..." though, since
the earlier bits are all irrelevant, now that the patches to enable the
IR part on the hdpvr are all upstream.
Also, watch out for a zilog rx thread pegging your cpu, there's a bug
in certain eras of lirc_zilog code, for which I just sent a patch upstream
yesterday. Optionally, if you're not using the rx bit, load lirc_zilog
with the module parameter tx_only=1.
