The worm driver is alpha-usable! I've stuffed everything that is needed into the kernel driver, including the logic to select between different vendor's quirks. Disclaimer: this has by now _only_ been tested on a heavily tweaked 2.0.5R system. I've done my best to retrofit it into -current, but i don't have a chance yet to test it in a -current environment.
