The bank bits (not PAGE bits) shouldn't matter AFTER you access the EEPROM
memory.  (Just as a note, the page bits (PCLATH) are set when you do your
call and restored on return.  Each page of these devices are 0xFF in length.
  Typically the page bits in PCLATH are manipulated when you modify the
program counter PCL, as in the case of a computed goto.  Otherwise, you
really don't have to worry about PCLATH much.)

Of course, whatever you access after you return will have to have the bank
bits set appropriately.  You don't have to reset the selected bank to 0
before you return, you can do it afterwards.  This shouldn't have caused any
errors with this routine.
