I'm not very much acquainted with SDL, but from what you describe, it is possible that you select a bad pixel format, either by providing some ill arguments to SDL or (less likely) a bug in SDL. That would explain why one program works different from another on the same machine.

It is very possible to select a pixel format which will generate non-accelerated OpenGL 1.1 contexts. PFD_SUPPORT_GDI is mutually exclusive with "accelerated OpenGL" and "anything higher than 1.1".

As for the "evil Microsoft plot to end OpenGL", this was surely something that was on the table when Vista was conceived, but the massive uproar that followed quickly put an end to that. Microsoft, like Intel, has gone Rudi Dutschke's way since then.

All in all, if someone doesn't have an IHV driver installed, it's questionable whether you really want them as customers. I'm not talking of the latest bleeding-edge drivers, but, you know, anything at all.
They must either be quite poor (not able to afford a $10 card!?) or quite stupid. In either case, you probably don't want them as customers. The poor won't pay you, and the stupid will cost you more in support than the revenue they bring in.
