In my earlier patch to the m68k fmovem disassembler, I repaired the register 

naming for fmovem, while breaking it for fmove. We probably never will
see normal fmove in the kernel, nevertheless it should be corrected while
somebody remembers.
Besides, the correct patch is smaller and thus easier to verify than the
origininal one.
