You are working too hard from old information. Do not attempt to load
i915kms.ko. Do not attempt to load drm2.ko. For the past months the
drivers have been fixed to automatically load all needed drivers and
kernel modules when Xorg is started. My Sandybridge behaves just like
your system if I try to manually load i915kms.ko. Screen goes black
and that is the end.

Oh, and you didn't mention libdrm. It should be built with WITH_KMS, too.
