This is the register for the 68881 on a plain (Mega-)ST/STE. This is
not supported by Hatari yet. Hatari only supports the advanced FPU
coprocessor that is handled via Line-f instead (I think it's currently
available in 68040 mode only).

I assume this is just testing for available hardware since hardly any
ST has been shipped with this FPU and Magic certainly also runs without
it.
