Indeed. Logically, FNINIT should have been extended to initialize it all - - it is a security hole that it doesn't initialize MMX properly. Alternatively, for SSE only, an INITP instruction could have been added that an SSE-enabled OS can use at the time OSXFSR or whatever that flag is called is set.
