My advice: change your plan.

I don't recall seeing any AVR that can directly access external code 
memory.  The AT90S8515 (which is not recommended for new designs, by 
the way), supports external RAM that is in the data space but not for 
code space.

If you need more code space, why don't you switch to a mega16 or 
mega32 which have 2x and 4x as much code space?  They're also faster 
and cheaper and have more capabilities than the AT90S8515.
