Yep, sorry, should have mentioned that.

The place for it is probably the lirc initscript. Set lirc-decode-only
on lircd init, restore in-kernel-decode on lircd halt. This is what is
being done in the Ubuntu packages right now, and what I think I'll do
in an upcoming Fedora lirc package update.

Kernel change. Several IR drivers have been rewritten for a the new
in-kernel IR stack, including the formerly lirc-only streamzap and
mceusb drivers. For raw IR devices, both in-kernel and userspace
decode w/lirc is now possible.

Yep, we're in a bit of a transitory state right now.
