[linux-dvb] FusionHDTV5 IR not working.

I have a DViCO FusionHDTV5 RT Gold, with an IR sensor that connects to
the back of the card.  The remote is a "Fusion Remote MCE".  The video
capture stuff works just fine, but I've had no such luck with the
remote.

According to this commit, it looks like my setup is supposed to work:

When I enabled debug output for ir_kb2_i2c, this line caught my eye:
ir-kbd-i2c: probe 0x6b @ cx88[0]: no

I also enabled i2c_scan in the cx88xx module, and saw this:

cx88[0]: i2c register ok
cx88[0]: i2c scan: found device @ 0x1c  [lgdt330x]
cx88[0]: i2c scan: found device @ 0x86  [tda9887/cx22702]

Does anyone know how to hack up this driver to determine where the
remote is hiding?  Let me know if any further info is needed.
