sys/arch/i386/include/npx.h: revision 1.23
The FPU Tag word is a 16bit register, in FPU (387) mode it
defines 2-bit tags for each FPU data register, in MMX mode it
defines 1-bit tags for each data register. The single bit
tags are stored in the lower 8 bits and thus in the first byte
of the save frame.
See amd64/include/fpu.h and the IA-32 Software Developer's manual Vol 2A.
