I'd argue for putting the split at either 386 vs 486+ (the latter at least has a math copro and CMPXCHG), or at 386-pentium vs 686+. I say this because the original pentium didn't introduce a lot of new features other than the two pipelines for which you only need some insn scheduling that's fully compatible with the 486, and IIRC wasn't sold nearly as well as the various flavours of the 486. In other words, if you use 486-compatible instructions and pentium scheduling, you're already taking almost full advantage of the pentium. It makes therefore little sense to group the original pentium with the later architectures.
