Well, the problem on Fedora is that you are using the mesa driver. This 
does some basic GL stuff but don't expect it do anything more than 
render some polygons. You'll need to opensource ATI driver which gives 
you more GL functions, or you could try out the driver of ATI. About 
Windows, the OpenGL version 1.1.0 has something to do with the version 
reported back by the OpenGL library itself. This will never report any 
higher than 1.1.0 I think. You'd probably get a better idea as to why 
this happens when you google for it.

You might have better luck trying out the ARB functions (glGenBuffersARB 
and glBindBufferARB). These should work if your OpenGL installation is good.
