Programming the data EEPROM as others have suggested seems like the
easiest answer. Alternatively you could just read the EEPROM to see if
those locations hold what you expect them to. If they don't, load them.
Another (much more complex) way would be to make your code load the
values the first time it's run, then modify the program memory to skip
those instructions forever after.

Seems like a lot of work though.
