i965-va-driver 1.0.1-3 (libva-driver-i965) - IS NO INSTALLED
is driver with support for hardware acceleration 
YES ? 
Can I install this driver, if it is for i965? 
 I use 
*lsmod | grep ^i915

If I want to install the driver with support for hardware acceleration, should I remove xserver-xorg-video-intel driver ?

libva1 - is not driver ?
