The answers are No, No and The scheduling is independent of the
instruction set. However, _scheduling_ for an i686 (i.e. -mpentiumpro)
might (or might not) improve the speed (and the programs will still work)
compared to scheudling with -mcpu=k6, so experiments in that direction
might be worthwhile.
