The old external iSight seems to have some power issues. People have gotten it to work on new Macs with FW800 ports, but usually not when connected directly (with the appropriate cable or dongle), but rather by daisy-chaining it through another external FW device or an ACD.
I know a guy who got it to work on a new MP, but he attached it to the FW400 port of an external drive and then hooked up that drive to the MP with a FW800->FW400 cable.
I guess it's not FW800/FW400 per se that's the issue (it shouldn't be either), but rather the new ports not delivering enough power. An external device (drive, ACD, FW hub) with its own power supply might be able to overcome that.
