This will interfere with the alternative use of LIRC drivers (which work
in more cases that ir-kbd). It will thus break some peoples' use of the
driver. Also we have better information on what i2c addresses needed to
be probed based on the model of the device - and some devices supported
by this device are not from Hauppauge so you are making a too-strong
assumption that IR should be probed this way in all cases. Also, unless
ir-kbd has suddenly improved, this will not work at all for HVR-1950
class devices nor MCE type PVR-24xxx devices (different incompatible IR
receiver).
This is why the pvrusb2 driver has never directly attempted to load
ir-kbd.
