We must be reading my mind, because I did exactly that last night. I did find a very small discrepancy, with about 2 (maybe 3)millimeters more space between the string and seat tube on the drive side. Not to happy about that either, but figure I can deal with it for now (unless you or anyone thinks that is too much. I have no experience with this).
Thing is, I'm not sure how frame alignment would affect the distance from the cranks to the seat tube, since they are mounted in line (vertically) with the seat tube? Am I missing something?

You know, I never even considered the possibility that it was asymmetric, but after looking around a little I think that might be a strong possibility. I found this link, which is for entirely different (and older) BB's, but makes me think the general practice continued on:
