umm that's why, I had specified i810 in xorg.conf before the upgrade, and so that's why Xorg was refusing to start, after running "dpkg-reconfigure xserver-xorg", "Intel" driver is being used (although not explicitly specified on xorg.conf, but I shows up on Xorg.0.log as being used).
My new (working) xorg.conf produces the attached Xorg.0.log.
