Notice that this is not really true, as there is no free OpenGL acceleration for any of the newer graphic cards coming out right now. The fastest graphic card with full free acceleration is the radeon 9000, which is now two generations old. This means that there is no acceleration outside of the x86 world, since neither ATI nor Nvidia are ready to build their proprietary drivers on anything else than x86. As long as this doesn't change, stating that we have an accelerated API for OpenGL in linux is not only dead wrong, but is leading us in a dangerous direction, where we will depend on a non-free component in the kernel and were we are going to forget about graphic support on anything non-x86.
