Start only second stage in console mode

Hello everyone,

I have a autoyast setup where I would like to install a headless server.

The machine starts an Xserver in Stage 1 of the installation process 
just fine and installation begins (a monitor is attached but turned off).

After RPM installation and rebooting/kexec into stage 2, starting XDM 
fails for some reason. As the machine is supposed to run headless in 
console mode anyway, I would not care at all. I even disable XDM 
completely later on as it is not needed.

But I seems like the second stage fails to start due to XDM failing.

Instead of fixing the reason for XDM failing, I would like to tell the 
*second* stage ahead of time to simply start in console mode.

Is this possible somehow?
I.e.: start stage 1 with X enabled, start stage 2 with X disabled in 
console mode.

The AutoYast configuration options for services is done at the end of 
stage 2, which is too late for this case.

Thanks for any suggestions!
