I wonder if the patch below is all that is needed...
Nope. Does not work here:

$ lsinput
protocol version mismatch (expected 65536, got 65537)
Heh.. I just noticed something *new* in the bootlogs on my system:

kernel: Registered IR keymap rc-rc5-tv
udevd-event[6438]: run_program: '/usr/bin/ir-keytable' abnormal exit
kernel: input: i2c IR (Hauppauge) as /devices/virtual/rc/rc0/input7
kernel: ir-keytable[6439]: segfault at 8 ip 00000000004012d2 sp 00007fff6d43ca60
error 4 in ir-keytable[400000+7000]
kernel: rc0: i2c IR (Hauppauge) as /devices/virtual/rc/rc0
kernel: ir-kbd-i2c: i2c IR (Hauppauge) detected at i2c-0/0-0018/ir0 [ivtv i2c
driver #0]

That's udev invoking ir-keyboard when the ir-kbd-i2c kernel module is loaded,
and that is also ir-keyboard (userspace) segfaulting when run.
Note: I tried to capture an strace of ir-keyboard segfaulting during boot
(as above), but doing so kills the system (hangs on boot).

The command from udev was: /usr/bin/ir-keytable -a /etc/rc_maps.cfg -s rc0
