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

Updated xorg-x11-drv-ati packages that fix several bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

The xorg-x11-drv-ati packages provide a driver for ATI graphics cards for the
X.Org implementation of the X Window System.

The xorg-x11-drv-ati packages have been upgraded to upstream version 6.14.2,
which provides a number of bug fixes and enhancements over the previous version.
(BZ#713766, BZ#634238)

This update fixes the following bugs:

* The ATI ES1000 graphics devices had limited Video RAM (VRAM) and were
restricted to an 8-bit color depth for the text console. As a consequence, the
graphical boot screen was unavailable on systems using these graphics devices.
Such systems could become unresponsive afterward and had to be rebooted. With
this update, the source code is modified and the installation with graphical
user interface (GUI) can be successfully completed. (BZ#588918)

* Due to the driver being too verbose, error messages about failed write
attempts could incorrectly appear when booting the system on i386 architectures.
The messages could be safely ignored and the system eventually booted
successfully. To avoid user confusion, these messages are removed with this
update. (BZ#615550)

This update also adds the following enhancements:

* This update adds support for the AMD FirePro M5950, AMD FirePro M8900, AMD
FirePro V5900, and AMD FirePro V7900 graphics cards. (BZ#675297)

* This update provides the firmware files which are required by AMD Radeon HD
6000-series and AMD's Accelerated Processing Unit (APU) platforms. (BZ#713622)

All users of xorg-x11-drv-ati are advised to upgrade to these updated packages,
which fix these bugs and add these enhancements.

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