Sun's RTF or release notes document this -- the label occupys the first sector (track?) on the disk, and using the normal a partition as swap overwrites it; it seems that the filesystem code skips over it. Their solution is to make a 1 cylinder a partition, then have b go from there to the end of the disk, and use b for swap. I suspect that making the label with the a parititon starting at cylinder 1 instead of 0 would work as well.
