LiveCD using vesafb or vesafb-tng

[DeepBlueSky]

Back again with another problem :

Booting from the LiveCD my 2 monitors connected to a single Ti4000 showed the console cloned and I liked this. Now booting my 2.6.9 kernel with vesafb tng it is switching always that monitor off thats connected to the DVI output (out of sync but that isnt really true. Depends on where I connected it). Furthermore the swichted off monitors shows some strange sync values, no idea where those come from. The xserver does this in the reverese order. I know I can toggle this with xserver somehow but that's not the question. Wanna get this damn console cloned to both
My guess is, the liveCD boots with vesafb only and thats working with 2 monitors. But 60hz isnt really the way so is there any workaround getting things cloned with tng?

Thanks again,
