I would be interested to find out, especially, what side Batman would be in. There are aspects of him that would be pro-registeration (hey, keep a track of all those superheroes ....and think of his past with his files on the Superfolk, plus the whole OMAC/Brother Eye thing). And there are other aspects that would be strongly anti-registeration (distrust of the system, distrust of everything for that matter).
Although if people like (say) Martian Manhunter and the Flash were pro-reg, then it would be easy to round up a good deal of the anti folk (MM scanning the globe, and giving telepathic links to a blitzing Flash ....although that might not even be necessary since MM himself can blitz 97% of the ppl he would come across).
Depending on how the sides are populated, registeration in DC would either be over very quickly, or never succeed at all.
