Restarting bluetoothd does the trick.  Granted stopping & restarting
daemons my seem a bit OTT, but its a quick process so it shouldn't
introduce a noticeable delay.

There is also the option to use LIRC with the devinput[1] driver, which
takes is input directly from /dev/input/eventX allowing you to use any
keyboard/mouse as an LIRC input.  This means you can then just configure
LIRC to have different mappings for Myth vs XMBC

However the problem I found with this method is that the
/dev/input/eventX only gets created when the PS3 remote connects for the
first time after a reboot, meaning you can't start LIRC until you've
pressed a button on the remote (otherwise LIRC just exits as it cannot
find the device).

I assume its possible to do some jiggery-pokery with udev to reserve the
device so it appear before it actually pairs.  Or write some script that
waits until /dev/input/eventX exists,  before LIRC is started.

But as I didn't need to control two different programs I didn't see any
advantage in using LIRC in my situation, so I just changed to using the
/etc/bluetooth/input.conf method instead.
