I have a 386/25 that is about a year old, it has the Sigma-Sigma sign on it. I have also looked at several brand-new 386/25's that does not have this sign. I have not looked closely at our 386/33. There is a program called Check-It (offhand, I forgot who makes it. It is not PD or shareware). This diag program will check a 386 CPU for the 'pre-sigma- sigma' bug. I was under the impression that the 'pre-sigma-sigma' bug was fixed before the 33mhz part was out. Or even before the 25mhz. But I have no REAL information to back this up.
