0528-Correct-a-NULL-pointer-deference.patch

  I will add this patch to Mandriva's X Server, but
maybe a similar patch could also be added to upstream
X Server, as it apparently fixes a crash that is caused
by hardware in the market, when running an application
that queries/uses XFree86-VidModeExtension.

  Note that the report about the X Server killing the
application and continuing running is a Mandriva only patch
http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/x11-server/current/SOURCES/0504-SAVE_CONTEXT-Mandriva-Custom-X-Server-patch.patch?revision=209187&view=markup

  Maybe a proper patch, not really to try to remediate
the problem of no edid information available, but for
consistency would be to ensure
hw/xfree86/modes/xf86Crtc.c:xf86SetScrnInfoModes()
is called at the proper place, and hopefully, this
way, both randr and the vidmode extension would work
together and not conflict.
