Hi,

you might also try bitbanging using the ftdi_syncbb programmer type. (files
ft245r.[ch])

The FT2232D should implement synchronous bitbanging the same way as the
older chips do.

However to use inverted pins you need to implement them first. Also there is
no support for buf pins at the moment.

I think, that is not possible. It is not even possible to remap the 
signals to other pins, due to "hardware acceleration" by the MPSEE unit.

Could you solve the problem in the hardware, by using a single invertor 
gate (e.g. in SOT23-5 package) ?

BTW, which avr chip uses such a strange way of programming?
