Sorry, I forgot that some other changes in the I2C code (e.g. no busy
waiting) went along with the speedup.
So, you'll have to wait for our next release (could be a while) 
or compare the current code yourself with the stuff in the linuxtv
driver version.

Thanks.  Which area of the code should I look at for the busy wait loop?

Bob.
