Hi,
Regarding option 1, yes you need to compile the hdpvr module with lirc-zilog
"enable" for that you need to patch the hdpvr source with the following
http://wilsonet.com/jarod/lirc_misc/hdpvr-ir/hdpvr-ir-enable.patch

you may also refer directly to Jarod's website http://wilsonet.com/?p=40

When I did that, it was working the first time. Since then it seems I
screwed my system, re-install it but never got /dev/lirc0 back. Still give
it a try.

Option 2
Yes it should work directly.
I've an harmony one, which was working with a "dirty" IR receiver given with
a first price remote. No need to have the zilog for this.
