xorg-x11-drv-nouveau bug fix and enhancement update

Updated xorg-x11-drv-nouveau packages that fix one bug and add one enhancement
are now available for Red Hat Enterprise Linux 6.

The xorg-x11-drv-nouveau utility provides the Xorg X11 Nouveau video driver for
NVIDIA graphics chipsets.

This update fixes the following bug:

* Prior to this update, one process was used to scan for all defects. As a
result, xorg-x11-drv-nouveau packages did not build without patches against its
supporting components. This update scans defects in downstream patches
separately. Now, the packages build as expected when not all downstream patches
are present. (BZ#708500)

This update also adds the following enhancement:

* This update adds the updated Xorg Nouveau driver for NVIDIA GeForce/Quadro
hardware to the xorg-x11-drv-nouveau package. (BZ#713768)

All users of the Xorg x11 Nouveau driver, are advised to upgrade to these
updated packages, which fix this bug and add this enhancement.

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
