If you want to use the IR blaster on the PVR-150, you need to
correctly install the firmware file, which is indicated on the Ubunty
HOWTO. Do you have it installed in /lib/firmware? The LIRC module is
not locating it, which is why it is failing.

If you only want to use the IR receiver with your remote, you don't
need to load the lirc_pvr150 module at all, as the lirc_i2c module
should handle the IR receiver.

I'm also quite sure you don't need both lirc_i2c and lirc_pvr150
loaded at the same time, as the pvr150 module contains both the IR
receiving and transmitting functionality.
