Here is an update with the problem that I had with my nvidia Quadro 900 
XGL running chimera and freezing the system.

It was a hardware problem with the card (it seems that the fan was not 
working and something got burned ??). At the beginning only OpenGL 
applications such as Chimers or Google Earth  were causing trouble 
freezing the system. Eventually display problems appeared all the time 
regardless of the application. I replaced the card (for an ATI Radeon 
9550) and now everything seem to work fine

Thanks for the previous suggestions
