Wow.  Found this via Pharyngula-- (a great site all on its own, by the way, as long as you don't mind atheism).

A fossil of a snake with two hind legs has been found in Lebanon.  One hind leg's bones were visible in the fracture plane of the fossil, the other was buried in the rock that cradled the fossilized bones, and  was imaged with an intense beam of x-rays from the Grenoble (France) synchrotron.
The 85cm-long (33in) creature, known as Eupodophis descouensi, comes from the Late Cretaceous, about 92 million years ago.
(For comparison, amphibians ventured onto land about 360 million years ago, birds showed up about 150 milliion years ago and the non-avian dinosaurs died out 65 million years ago.)

However, according to Wikipedia, snakes with hind limbs are already known from the fossil record.  Plus some existing speciles of snakes, like pythons and boas, have vestigial hind legs called anal spurs that are used in mating.
