I think I had a similar problem w/ an i915-based system. There were several 
things buggy
at the time:

- using a PS2 keyboard caused very slow Xorg startup => installed a USB keyboard
- DRM was failing => disabled DRI/acceleration in /etc/X11/xorg.conf
- PCI bus probed incorrectly => make explicit in /etc/X11/xorg.conf

I find creating a xorg.conf.new file using 'Xorg -configure' then tweaking one 
thing at a time
and loading it with 'Xorg -config xorg.conf.new' helps with chasing down Xorg 
issues.

Good luck!
