Would it be reasonable to create a single byte section in the .LKR file,
just to hold the WREG on interrupt.

Where multiple banks exist (but no common memory) this section would be in
one of the banks and the other banks would be 'shorted' by omitting their
corresponding byte.

When only one bank exists you have nothing special to do.

When you have shared memory you put the WREG save spot in the shared space
and reduce the size of the 'user-visible' shared area by the one byte.
