Re: So what exactly have they done inside and what will be the consequences?
So its not likely to be "We'd like n new chips, please." Rather "ARRRAGH - you barstewards - you've borked the pinouts. We'll need n new boards as well"
I read it more as being the case of "we'd like new chips please", unless you were using the LPC pins as GPIO in which case you would need to do a redesign given you'll be needing additional logic for the functionaliity you needed the GPIO for.
