@melott:
In your S:Startup-Sequence, do go you call ksremap with the argument QUIET (ksremap QUIET)? If that doesn't make any difference, have you tried executing it from a shell when running Workbench to see if it reports an error of any kind, thus outputting something that produces the issue?
Btw, if you don't need the speed, I am willing to trade my GVP G-Force030 accelerator for your Tekmagic 060 ;=).
