What do you need to snub? The boost converter clamps into the output. If you looking for a "snubber" to reduce turn-on losses, you might look at Unitrode's (TI's) PFC data sheets and app notes for active snubber information or if you don't mind burning power, a small inductor in series with the switch with a reset resistor and diode across it might help. Good Luck.
Unitrode has a GREAT summary article in the design seminar stuff on active and passive snubbers. The non-dissipative stuff is awkward at first, but just use the same thinking as you would for a commutation circuit in examining their function and you'll get the idea. The small current in the L's means you can usually get away w/a standard/cheap L that keeps the cost and space reasonable to implement.
