Some more suggestions, in addition to Daniel's:

That's

	if (active &&
	    !intel_pipe_config_compare(dev, &crtc->config, &pipe_config)) {
		WARN(1, "pipe state doesn't match!\n");				<---
		intel_dump_pipe_config(crtc, &pipe_config,
				       "[hw state]");
		intel_dump_pipe_config(crtc, &crtc->config,
				       "[sw state]");
	}

And there's that taint P again due to the vmware modules.

I know that you tried without the vmware modules where your kernel
wasn't tainted but then you got a #GP which could be something entirely
different. But now you're hitting some sanity-checking code which could
mean there's some corruption happening.

So, can you reproduce that exact same warning, i.e. this one:

WARNING: CPU: 1 PID: 4142 at drivers/gpu/drm/i915/intel_display.c:8292 check_crtc_state+0x5cf/0xa60 [i915]()
pipe state doesn't match!

*without* the vmware modules installed?

Also, it wouldn't hurt to try the shiny new 3.12.

HTH.
