Given I can't find any pictures of the mc68032, I'm guessing it was either mythical to begin with, or it was a prospective product Motorola planned to offer but never ended up releasing it.
EDIT: AHA! It WAS a real product, but it is called mc68012 and is mc68010 derived! It is 84-pin PGA only. See
http://www.cpu-world.com/CPUs/68012/LN
from the data sheet
The MC68012 is an expanded address
range version of the M C68010 with the additional address pins A24-A29 and A31. A30 is not included
due to packaging restrictions.
I mis-remembered the number of address bits.
