I guess ATmega1281 will be similar to ATmega128. Application note
AVR097 says: "ATmega128 and ATmega1281/2561 are designed to be a pin
and functionality compatible sub family.". The appnote also says that
TIMSK register changed for timers 1 and 3 and that timers 0 and 2 are
completely swapped (I guess those guys at Atmel were smoking pot at
the time), see Timers chapter. There is no documentation on how to add
a device support in general or how to add timer support in particular.

I did tinker around peripheral creation before, I think I can add
timers to a device.

Either send the files to the list or create a new entry in savannah
patch tracker. I suppose you did not need to patch other files.
