Yes, but I don't know if perhaps -march=k6-2 should be used as a fallback, as suggested in [1]. BTW: You can change optimization bitmasks and cost tables in gcc/config/i386.c to find out what effects runtime performace, but without access to a target processor, there is no way to resolve runtime regressions.
