The intel driver supports panning for all chips it supports (excluding
the ancient i810 series I suppose).  If you're seeing variation among
chips it's because you're not running the same driver [1].

RHEL 6.1 includes support for Sandybridge chips, which is the useful
name corresponding to "HD Graphics 2000".  CentOS presumably does too if
they haven't broken what I put in RHEL.
