I can confirm Seawane 100% just popped a spare usb2 card in i had ALi M5273 (Uli) works out the box. Only issue i have is keyboard not seen in bios (have to swap port for bios entry). Also Nvidia do osx drivers for this if anyone had issues. What i have noticed is it seems nippier than b4. Itunes next track etc on keyboard seems to change in a fraction of the time. Sewanr Thanx your a star
