After scouring the mailing list, I found someone who said they had hacked 
SDL to use a refresh rate that they specified.  I could do that, but I 
was wondering what would be a more general, and correct solution.

As per my previous email, I think the change in X is that it now sees many 
more modes than it did before, probably because it gets them from the 
monitor directly and not through the XF86Config file (though modelines 
listed there are used as well).
