II've had the same error message after I upgraded from Kubuntu 10.04 to 10.10 (with updates) yesterday. My PC has two Radeon cards (RV350 and RV370).
After many hours trying bring my system to live I've found that in my case the cause of problem was:
Load "v4l"
option in "Module" section of this file but unfortunately I don't see it in yours xorg.conf file.
Commenting this line fixed KDM (and Xorg) start.

I'm hitting this with Xephyr, just installing xserver-xephyr and trying for example command "Xephyr :2" triggers this assert:

Xephyr: ../../../../include/privates.h:122: dixGetPrivateAddr: Assertion `key->initialized' failed.

xserver-xephyr version 2:1.9.0-0ubuntu7 on 32-bit Maverick with latest updates.

However, xserver-xephyr 2:1.9.0-0ubuntu7 works well on *64-bit* Maverick.

[Maakuth (markus-vuorio)]

To amend my previous comment: it works fine when running Maverick natively on my Thinkpad X60 (Intel 945GM GPU), but fails when running inside VirtualBox with guest additions installed from virtualbox-ose-guest-x11 package, as well as with the guest additions shipping with nonfree VirtualBox.

Without guest additions, it works fine. Hmm, guess I should go bother the VirtualBox guys then.
