I have done some testing, and found that specifying the use of the vesa driver in Xorg works around the problem. All the gnome-system-monitor, notify-osd and even cairo-dock come back. Hope this may help a bit.
Here is my /etc/X11/xorg.conf:
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
