asim_whatever definitely does not belong to Kick/WB 3.1.
What do you mean by "still on the system"? How do you know? Where do you see it?
IIRC asim_atapi is/was a replacement device driver for the atapi device by Asimware (i must have the handbook and disks for that somewhere..). Was a commercial product. The cd driver for that device had nice features. But it definitely does not belong to a vanilla 3.x installation.
