Actually I wrote a GL_NVX_gpu_memory_info patch as well, didn't have
time to send the mail to here yet. The patch I wrote is a bit
different and I think that's how it should work. You have to keep the
current code as it is. After the gpu / amount of video memory have
been selected AND if no gpu memory override is set in the registry
(there can be good reasons for not exposing all video memory) then if
the nvidia extension is around, the amount of video memory should be
overridden. Let me dig up the stuff I made.
