Yes, this is what I've been talking about.

The 24xxx devices don't have a dedicated IR receiver chip on its internal 
I2C bus.  The 29xxx devices did have this, and this is what the lirc 
driver (or ir-kbd-i2c.ko) looked for and operated.  To make this work for 
24xxx devices, the I2C adapter driver within the pvrusb2 driver now 
intercepts commands to the non-existant I2C chip and then emulates the 
chip's behavior via corresponding commands directly to the FX2 (where the 
IR reception is actually implemented).

I released code for this in the current standalone (20061007) snapshot, 
but until tonight I hadn't updated the in-V4L version of the driver.

If you have this working with a driver earlier than this, I'd sure be 
curious to know how you did it :-)
