I'm not sure if the version at Macally is different to the one posted here (a difference of 20k or so), but my IceKEY keyboard is working perfectly! Volume keys and Eject key all fully functional! Am running Leopard on MBP (luckily Leopard came installed, which may make a difference). Will even sleep/wake from sleep with full functions (my pre-Leopard iBook dual-usb would always wake from sleep due to the keyboard).

So relieved - the best keyboard I've ever tried, so I'm glad this driver has it running properly.
