Not sure if this is related, but when modding the Colour Classic to fit a PPC board in it, you have sever one of the wires on the floppy cable to prevent the new PPC board from reading the floppy drive continously - if that pin is left connected, the floppy drive will infinitely "eject" no matter whether there's actually a disk in it or not ... Again, I'm not sure if this is the same issue, but I figured it's worth a thought.
