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.

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?
