Since 11.4 (?) we have the following info in the release notes (time to add
this to the official docs now--13.2 and later).  Frank, please reassign as
appropriate:

  <!-- FIXME -->
  <!-- bnc#595569, 621469, 673964, 781700 -->
  <sect2 id=3D"sec.114.kms">
   <title>Initializing Graphics with KMS (Kernel Mode Setting)</title>
   <!-- <para>CHECKIT:12.3</para> -->
   <para>
With openSUSE 11.3 we switched to KMS (Kernel Mode Setting) for Intel, ATI
and NVIDIA graphics, which now is our default. If you encounter problems with
the KMS driver support (intel, radeon, nouveau), disable KMS by adding
<literal>nomodeset</literal> to the kernel boot command line.

To set this permanently using Grub 2, the default boot loader, add it to
the <literal>GRUB_CMDLINE_LINUX_DEFAULT</literal> kernel default load
options line in your <filename>/etc/default/grub</filename> text file as
root and running the terminal command
   </para>
   <screen>sudo /usr/sbin/grub2-mkconfig --output=3D/boot/grub2/grub.cfg</scr=
een>
   <para>
for the changes to take effect.  Else, for Grub Legacy, add it to the kernel
command line in <filename>/boot/grub/menu.lst</filename>, also done as root.

This option makes sure the appropriate kernel module (intel, radeon,
nouveau) is loaded with <literal>modeset=3D0</literal> in
<filename>initrd</filename>, i.e. KMS is disabled.
   </para>

   <para>
In the rare cases when loading the DRM module from <filename>initrd</filename>
is a general problem and unrelated to KMS, it is even possible to disable
loading of the DRM module in <filename>initrd</filename> completely.  For this
set the <literal>NO_KMS_IN_INITRD</literal> sysconfig variable to
<literal>yes</literal> via YaST, which then recreates
<filename>initrd</filename> afterwards. Reboot your machine.</para>

   <para>
On Intel without KMS the Xserver falls back to the
<literal>fbdev</literal> driver (the <literal>intel</literal> driver
only supports KMS); alternatively, for legacy GPUs from Intel the
"intellegacy" driver
(<systemitem>xorg-x11-driver-video-intel-legacy</systemitem> package) is
available, which still supports UMS (User Mode Setting).  To use it,
edit <filename>/etc/X11/xorg.conf.d/50-device.conf</filename> and change
the driver entry to <literal>intellegacy</literal>.</para>

   <para>
On ATI for current GPUs it falls back to <literal>radeonhd</literal>. On
NVIDIA without KMS the <literal>nv</literal> driver is used (the
<literal>nouveau</literal> driver supports only KMS).  Note, newer ATI
and NVIDIA GPUs are falling back to <literal>fbdev</literal>, if you
specify the <literal>nomodeset</literal> kernel boot parameter.</para>
