I've got cocolino's on pretty much all my machines. they work fine in early startup, outside workbench, inside workbench, games, etc. etc.
all the "driver" disk is for is the mousewheel and third mouse button if i recall correctly. as i've not bothered with the "drivers" since i found some setups had issues and would freeze when they were loaded at WBstartup. but as usual, your mileage may vary, and all software/hardware setups are different in some way.
but otherwise, i've found they're a fine piece of kit. once you go optical, you'll be wondering how you stuck it out with a ball mouse for so long
