The 68882 is only a 68 pin PGA, the unlabelled socket is much larger.  Not only
that, but there's no reason to have a 68882 sitting right next to the card
connector, if the 68030 is all the way over on the other side of the machine.

Didn't notice the packaging, but Motorola is starting to offer these parts in 
cost reduced packages; perhaps this was an early one without markings yet.
