could we turn that option back (if proven that it is it)?

To test this I would need to run the new kernel without the kernel atyfb 
and see if then Xorg starts.
I asked for advice on how to, if it were grub or lilo I would know how 
to change the kernel parameters, but with Mac I'm less easy.

Thanks,
