As someone pointed out, it appears that X is reverting to the VESA
driver, in the above log. Yet, the xorg.conf states that:

Section "Device"
        ### Available Driver options are:-
        ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
        ### <string>: "String", <freq>: "<f> Hz/kHz/MHz"
        ### [arg]: arg optional
	Identifier  "Card0"
	Driver      "geode"
	VendorName  "Advanced Micro Devices [AMD]"
	BoardName   "Geode LX Video"
	BusID       "PCI:0:1:1"
EndSection

So it appears that GEODE fails to claim the device and X tries to
revert to VESA as a backup solution.

As a second test, I purged the VESA driver, leaving only GEODE
installed and rebooted. In that case, X freezes and it also takes the
whole system down with it.
