Type of the FPU

The upper WORD describes the type of the FPU in use:

 Bit-0:     SFP-004 or compatible FPU-card (68881 as a peripheral 
            component), if set.

 Bit-1..2:  68881 or 68882 as co-processor. This can be:

             0  =  Neither/nor 
             1  =  Exact type unknown 
             2  =  68881 
             3  =  68882 

 Bit-3:     FPU in MC-68040

 Bit-4:     FPU in MC-68060

The lower WORD is reserved for information about software support via 
the Line-F trap, and is at present not yet in use. According to Atari, 
a non-zero value indicates that Line-F support is present.
