Is there anyone who succeed to have dual LCD + HDMI screen working

[fab]

Hi,

Is there someone who succeed to have both LCD + HDMI screen working in dualhead or clone mode, on debian R5?
I tried all different wikis related to that stuff from Sunxi, but no way, it does not work.
LCD is working well alone
HDMI is working well alone.
But both at the same time, NO!

Any ideas are more than welcome...
