I don't think this is the root cause. I am seeing the exact same issue after upgrading a Sandy Bridge machine with on-chip-GPU to a recent -STABLE. Worked perfectly fine before with the abandonware-i915kms in base as well as with drm-legacy-kmod. Now both are showing a mere black screen, just like Nils reported. Maybe the recent MFCs of linuxkpi stuff broke something. I'll build some kernels and modules and see if I find the issue. Meanwhile, if it's been discovered (and fixed) already, let me know.
