I agree with fishy_fiz there - you might get away with Workbench type use with an 040 just bolted on and using the Commodore 68040.library, but an 060 will surely crash within minutes if they're not correctly set up. The 68040.library which is supplied as part of the OS is for the 040 cards manufactured by Commodore, but should be replaced by the appropriate library for your specific card. That will most likely flush out any residual issues with WHDload, and be equivalent to the 68060 as regards compatibility.
