I'm not sure how long its been up, but the Mark of the Unicorn site has a beta driver for the 828 firewire device up. I was running the OSX version of deck and it recognized the device and operated fine for a bit, but 20 minutes in it crashed. Since then, any program trying to operate with the 828 crashes as well... it is beta I guess. At least someone is trying!
