Hey guys,
I got airosnort in 3.3 to work but its a roundabout way of doing it

1.At bootloader type "knoppix single" ("knoppix 2" should also work)
2.When booted, type "startx", this will start the GUI (as root)
3.When booted, open a terminal and type "kismet", kismet should start and put card into monitor mode.
4.Start airosnort, select orinoco and eth0 (if eth0 is the orinoco card)
5.Click start and as card is already in monitor mode airsnort has no problems.

This works for me, hope it does for you too.
