I'm not an expert here, but I think you can enable 68882 emulation in 
68060 mode and sort of work around it. However, I don't know what kind 
of performance that would give.

It was suggested earlier getting the CT60 TOS going in Hatari 060 mode, 
that would solve this problem. But on the other hand, the 060 emulation 
itself maxes out at 32 MHz, so it's not going to look pretty no matter what.
