If the OS supplies an FPSP, you don't need to change anything in Hatari. Only thing that could be done is to add a setting that allows to emulate all FPU instructions, regardless of actual FPU in use. That would of course be not really correct, and might break software that tries to detect the FPU type using those instructions, but may make demo programs like hex pistol work again.

It supports 060 by detecting it, but there is no 060 specific build of it. And i'm not sure whether the FPSP will fit in the ROMs, given that they also have multi-language support. Might be easier to create installable loaders for them (remember that there are two different versions of FPSP, one for 040, another for 060).
