Roger:

That is *not* the same scenario.  We're talking about a jam-up 
immediately after the FX2 firmware has been downloaded.  This is very 
very early in the initialization process.  At this stage, the driver's 
I2C adapter has not been initialized and the rest of the kernel can't 
see the I2C bus.  This is long before any kind of communication with the 
chips on the device is even possible.  Therefore lirc simply can't 
interfere at this point.

And if you still don't believe me, heck, lirc isn't even *installed* on 
either test system right now!
