As the graphics is now handled by the kernel if KMS is used, this
dependency moved from the Xorg driver to the kernel, too.

Thanks. I already looked over the page, but missed the important bit. 
Now I can start the kernel, and get video output.  However, I get a
panic when the root partition should be mounted, because the SATA disk
is not detected.  At least there are no messages regarding sda.  The
DVD drive is detected, though.

Any further hints are appreciated.
