I understand that 10.10 / KMS does not use xorg.conf; however, I need to add the following to my xorg.conf in a Device section:

Option "Capabilities" "0x00000800"
Option "UseFastTLS" "off"
Option "KernelModuleParm" "locked-userpages=0"

However, /etc/X11/xorg.conf does not exist... Do I have to recreate one, or do I have to add this to a file inside of /usr/share/X11/xorg.conf.d/?

You'll have to build your own, 10.04 & newer releases do not have an Xorg.conf.

Just do gksudo gedit /etc/X11/xorg.conf, paste the section in, save it and it'll be created.
