It seems very difficult to get patches accepted.

The AT91 team tried, they gave up due to no repsonse.

I tried, and got everything rejected until Peter Pearse became custodian.
    Then I sent in few simple patches which got accepted.
     I have not had the time to do anything about it since then.

The AVR32 stuff uses basically the same peripherals as the AT91
and many drivers will be common.
Taking the Atmel patches to 1.2.0 and forwarding them,
   is not a good idea, because the AT91 should use
    drivers common with the AVR32

The AT91CAP9 stuff is now beeing processed in the patch system
and most of the stuff should be common with the AT91SAM9,
so once CAP9 support is there, I think it will be much simpler.
