Linux and Register Combiners

I use register combiners for rendering bump mapped planets in my space simulation Celestia . This works beautifully on Windows but I’m having problems with the Linux version. glXGetProcAddressARB appears to be returning valid addresses for the various GL extension functions, but when I actually try to call one, the program crashes immediately. Anyone have any suggestions?

I’m using version 0.9-769 of the nVidia drivers for Linux and a GeForce2MX. My program is also entirely C++, but I don’t think that should make a difference.
