This is not going to help, but for your information: I had a vanilla Solaris 10 11/06 and I applied the same patch bundle you're mentioning: I had many and funny problems related to Xorg, including Xorg -configure and xorgcfg not working any more and some errors detected in xorg.conf which were not detected before applying the patch. I think there were due to some missing module which probably was removed from xorg distribution. By the way, not being able to generate a xorg.conf automatically (because Xorg -configure was broken...) and not willing to loose time solving something that sould work out of the box... I simply removed xorg.conf and the detected configuration was satisfactory for me.
That's exactly what patches shouldn't do... I'm afraid of patching, now.
