You are miss understanding me, I mean you don't want to use the SSE
registers but still want to use the new x87 instruction, this is a x87
instruction after all and really nothing to due with sse3, except Intel
saying it is a SSE3 (really PNI) instruction.  This is just like monitor
really.  Really what Intel did was just renamed PNI to SSE3 without
taking into account what instructions affect SSE registers.
