Thanks, I'll add it again (with the diff you proposed):

<title>Initializing Graphics with KMS (Kernel Mode Setting)</title>
<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, add it to the kernel command line in
<filename>/boot/grub/menu.lst</filename>. This option makes sure the
appropriate kernel module (intel, radeon, nouveau) is loaded with
<literal>modeset=0</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,
there is the "intellegacy" driver
(<systemitem>xorg-x11-driver-video-intel-legacy</systemitem> package) 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 only supports KMS).</para>
