You are be able to do a Google search of site:bitcointalk.org "profile" "[address]"
The quotes will link to profiles and specify the address. Shouldn't that work?
That obviously works (i.e. "site:bitcointalk.org address", and even address only + bitcointalk), but if there was something like a cached version (i.e. someone has changed his address several times), then it's a bit different.
There's a reason for asking this, otherwise my Google Fu is pretty good, but it would spare certain amount of time.
