This is partly "our" fault the current libGL suffers from a lack of
vendor extensibility ... Ian has been doing some serious work on
making sure this doesn't happen for 6.9/7.0, and I believe ATI have
been in contact with him to avoid their having to ship a separate
libGL in the future..

Then we'll just have to convince nvidia that they are being silly
using their own one :-)
