It also looks like xserver (or maybe libgl) cannot load i965_dri and
instead it loads swrast_dri:

[kiesiu at beth ~]$ LIBGL_DEBUG=verbose glxinfo | head -n 3
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/swrast_dri.so
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes

[kiesiu at beth ~]$ rpm -q Mesa-dri-driver-swrast Mesa-dri-driver-intel-i965
Mesa-dri-driver-swrast-7.2-2.i686
Mesa-dri-driver-intel-i965-7.2-2.i686

Could someone else confirm if has similar problem with intel cards?
