Okay, but what exactly triggers the firmware counter?  Is it triggered 
by internally detecting the region - in which case hacking the firmware 
(dangerous, but possible apparently) would be the only way around it, or 
is it triggered via feedback from the software?  If it's triggered via 
feedback from the software, then it could be ignored....

As for five times, I think it actually amounts to four, because they 
count the first setting (not chosen by the purchaser of the hardware) as 
one, so the first time you change it, it's counted as two.
