Hrm. Should all be working then. Not sure what might be awry. Don't suppose you could boot a Fedora 12 live image on that system and see what it sees? The hdpvr module on there has the patches to enable IR, as well as the necessary lirc_zilog, so all you should have to do after booting is modprobe lirc_zilog, and it *should* be working. If so, then we know there's something not quite right with what you've got on the Ubuntu side. If not, that's good to know as well...

Yeah, there's definitely a need. Don't have time to do much testing right now myself.
