I do not think we should remove any at this point in time.

Looking at gcc-4.2.0/gcc/config/m68k/t-m68kelf it has a number of targets that 
I would not have expected to generate any different code. I think I might do 
some tests and report back to you. It does have the v3 and v4 support and I 
think we should add these.
