Arch not starting - no console login

Question

Hi guys,
I've been trying stuff for myself for some time now, but seems I need your help.
For a few weeks now, my Arch Linux i868/KDEMod-System is not starting anymore. Last thing I remember is to do an upgrade to the latest KDE(Mod) packages (4.5.0 I guess), but I don't think thats the problem. Here's what happens:
When I boot Arch, it just stops at some point towards the end of the boot process - soon after ntp and boinc daemons are loaded - with the message "Error opening display", and eventually error messages about vc processes respawning too fast - the virtual consoles 1-x, I guess. So no chance to login. The only reaction I get is the switch to runlevel 6 when pressing CTRL-ALT-DEL.
I thought it was an X11 issue and switched drivers from nvidia to nv to vesa, no success. I then disabled loading KDE in the inittab, no change either. Now I am down to runlevel 3, but still the same. I am a bit confused because I thought X shouldn't try to start anymore like this, but I still get "error opening display".
The grub menu Arch fallback option doesn't do anything different either. Next thing I thought about is using an older kernel, but there's just one in /boot. /var/log's don't look helpful to me either... excerpts at the bottom.
Any ideas?
Regards,

/var/log/Xorg.0.log is very long and without errors as var as I can see
