Usuallly it is kdm that talks to console-kit, since we do not use kdm
then uxlaunch should do that role. Distributions seem to launch desktop
sessions like this:
ck-launch-session dbus-launch startactive
I tried that in a x86 Meego image it the kde agent simply stopped
working (could not authenticate). I wonder why everybody on the Internet
suggests doing that, maybe uxlaunch does not support console-kit.

Have you tested downgrading polkit from 0.104 to 0.103?
