I had issues with some omnivision cameras, but they were indeed quite old. My 
rant was rather about not closing the door for 100kHz if it was ever needed. But 
like you said above, if it can be changed after applying the aforementioned 
patch, that's ok.

Thanks for clearing this up, sorry for pestering you.
