The BRK and RESET vectors are at different addresses.  RESET is
at $FFFC:FFFD and the BRK is at $FFFE:FFFF.  So if you aren't using
the last two bytes of ROM for data, etc, you can make them equal to
the RESET vector and use the BRK as a software RESET.  Just remember
that the BRK uses the stack (I think).
