Couldn't be.  No.  Never!  The 68882 is pin compatible with the 68881.
Completely.  100%.  Pop out your '881, push in your '882, and fire away.
Are you sure CSA is selling a tower board to run a 68882 in a 68881 
environment?  I can't believe it for a second.  The '030 is another story,
there's a complete pinout change there, not to mention a few other details
that have to be covered to run a 68030 in a 68020 system.

A good start.  But Moto tends to oversimplify the interfacing needed.  If
you were to build a 68020 board directly from the Moto application notes,
you'll run into trouble, at least on an Amiga.  The notes are pretty much to
get you started, and for that keeping things simple is a good idea.
