According to the picture in Unix World, the socket is for the "Bus Buffer
Gate Array".  Supporting this is the fact that if you look at the traces
from the bus connector, most go through that socket.

Also, in the Unix World picture, the 68882 is labeled with the Motorola 
insignia and something like 'Xx68882FM25'.  Its kinda strange that the
Byte picture has an unmarked chip for the FPU.
