I'd try launching xfce usfing a different command: "startxfce4
--with-ck-launch". In this way it will be xfce launching it's own
consolekit session. Also not running it through "exec" could slightly
influence things.

You could also use truss(1) to look at what is happening. It's noisy,
but very detailed. To launch it you should modify startxfce4 to launch
the Xorg server through truss and redirect output.

BTW have you had a look at Xorg log files in /var/log? Maybe you could
find something there too.
