getting TV-Out to wirk with i810 driver

[urubatan]

Hi, I have installed kubuntu in my laptop, a HP dv4100 series and every thing is working fine, but I can not get my TV Out port to work, it does not work with X and does not work in console too
when I press FN+F4 the television screen just flashes (with nothing understandable) and nothing more happens ...
And I can only use an external monitor to work if I start the computer with it already attached too ...
When I was using windows XP I pressed FN+F4 and it switched from LCD to external, both, and back (the external being a VGA display or the TV out)

how can I make kubuntu work the same way?

my xorg.conf created by the installer is bellow.
Thanks for any help ...
