The PhysX SDK is free. If you target Windows, your worst option would be 
to just use that, it seems?

Also, if there's really a case of big-guy-against-little-guy and there 
IS clear prior art, then the FSF might be interested in getting 
involved. However, patents are notoriously hard to read as a layman, 
every word in the claims matters. I haven't read the patent, but it's 
quite possible that all this kerfuffle isn't necessarily justified.
