Good Luck!  I spent three weeks trying to do the exact same thing, only
to give up and find another compiler vendor.  Most of the problems
revolve around the fact that the 68020 has a different cache mechanism
which includes a cache register, CAAR, that the 68040 doesn't have.
Since the '020 code wants to push/pop this register frequenctly
during kernel access, it was a pain to comment out.  After about
three weeks of trying, we found another Ada company that has a cross
compiler made specificly for the Force CPU40.  The company is
Systems Designers, located in the UK with a branch office locally
in Burlington, MA.  There product is a 68020 variant, tailored to run
specificly on the Force CPU40.  The only problem is that there
almost exclusively a DEC host site.  We couldn't get a UNIX to CPU40,
all they had was VMS to CPU40.  If you need more info on the company,
let me know.  Good Luck!
