ok, so I had an "older" D11S64 install CD and retried. Installation went as you said perfectly (besides the update stuff) and I even could use the kbd for installation.
Reboot went once (with errors) up to the login but could not use the USB kbd. Another reboot and it crashed from there on.

I had to use my serial connection as the USB stack is failing (locally).
