Tried 3.11-rc7 on Thinkpad X30 (first 3-11-rc tried on this hw). Works but i915 gives strange assertion failure with WARNING stack trace. This is new since 3.10.
It is still there with 3.12-rc1 but now I git around to bisecting it. This is the commit that introduces the warning.

drm/i915: set up PIPECONF explicitly for i9xx/vlv platformsMy apologies for not responding to your first report, fell through the cracks somehow. Can you please boot with drm.debug=0xe, reproduce the WARN and grab the full dmesg (please make sure everything from boot-up is in there). That's usually enough to figure out what's going wrong here.
I'd say it's a simple matter of forgetting about QUIRK_PIPEA_FORCE in i9xx_set_pipeconf().
