Could be wrong, but I remember something about a handy program called Conflict Catcher which was sometimes useful in situations like this before the Extensions Manager existed. It seems there are many inits, cdevs and extensions that are not quite compatible, and the success of some even depends on the order of installation. Hence the modern admonitions of disabling all extensions before loading, and the various tricks of adding a name prefix to change load order, I think. (I always love it when I boot with the shift key and then can't find the CDROM drive anymore.) If you can temporarly disable the many other non-Apple 6.0.8 additions you have made, you may find the control panel in question works, and may continue to work when the others are re-enabled.
