I think this can be fixed by inserting two dummy interrupt vectors
(1 and 3) between the real ones, like this:

#define SIG_TXBE   _VECTOR(4)

#define _VECTORS_SIZE 10

The datasheet clearly says that reset must be JMP or RJMP, and that
SIG_TXBE handler can start directly at address 8 (word 4), so using
RJMP there should be safe.
