Thank you. So if I understand correctly, you're saying I'm using nvfx, 
which upstream doesn't support anymore. While the long-term path is 
clear (use nv30 with Mesa 8.1+), for squeeze we have to decide what to 
do. As far as I can see, either we support nvfx for squeeze without 
upstream's help, or we prevent nouveau from doing hardware-accelerated 
3D on this hardware.
