Thanks, all.
Changing the tooltype to 2060scsi.device did it. I should'e thought of that.
I just went ahead and changed things to DH0: -> DH2:, terms I am used to. I have an assign to SYS: in my startup scripts, but not as early as it should be.
Actually, my startup scripts boot either WB1.3 or 3.1 on the same partition based on the ROM version - I have a switcher. Given that I am using the A2060 as the SCSI controller now, I can't really boot into 1.3 with that setup, I think, so I may just remove the extra script abstraction and keep to 3.1 always.
I do have an A1000 over on the other desk, so... :-)
