While I fundamentally disagree with this change, I'm not going to nack it. That said, this wasn't the issue I was concerned with. My suggestion was simply that you cannot assume that all devices that happen to have a particular demod and tuner combo will always use the same IF configuration. The PCB layout can effect the optimal IF. This is one of those things that (like many tuners in the LinuxTV tree) will probably work good enough to get a signal lock for whoever added the board profile, but will result in poor tuning performance (and a failure to work in less-than-ideal reception conditions). All that said, if somebody actually intends to hack on it, I can look up what the correct IF is for the 520e. Devin -- Devin J.
