The ioctl bits are already committed in my lirc git tree, they just
weren't being applied to the lirc userspace too, which is the result
of the breakage for 32-bit Fedora users. Shouldn't be your problem,
unless you're also running 32-bit with lirc drivers built from my git
tree. In either case, you can find all the userspace patches in
Fedora's lirc broken out here:

http://cvs.fedoraproject.org/viewvc/F-12/lirc/

The ioctl portability one is the most relevant, though I think I
screwed up and put a bit that should have gone in that patch into the
'remove obsolete modes' patch -- the #include <stdint.h> bit that
provides the uint*_t types.
