Wrong patch. That's for 2.6.30 and earlier. There are significant i2c changes in 2.6.31 that have to be accounted for. Use...
http://wilsonet.com/jarod/junk/hdpvr-ir/hdpvr-ir-2.6.31.patch
...or...
http://cvs.fedoraproject.org/viewvc/F-12/kernel/hdpvr-ir-enable.patch?view=markup
...instead.
That'd be why lirc_zilog isn't binding.
