I did have a look at the log files on my amd64 machine, but there's nothing in them when the screen and the text console stay black. Nothing in Xorg.log, .xsession-errors and kern.log. TBH I forgot to look into gdm.log. On the Intel-based notebook I didn't look into .xsession-errors and gdm.log. Xorg.log and kern.log don't contain any hints about what's going wrong, not even anything from the - usually more verbose - i915 kernel module KMS/GEM code.
