For me, things improved on amd64 (haven't tried i386) today with

P sys/external/bsd/drm2/dist/drm/i915/intel_bios.c
P sys/external/bsd/drm2/include/linux/dmi.h
P sys/external/bsd/drm2/include/linux/init.h
P sys/external/bsd/drm2/linux/files.drmkms_linux
U sys/external/bsd/drm2/linux/linux_dmi.c

for the first time my Ivy Bridge laptop and Sandy Bridge laptop booted
into a usable state! (failed last night without those patches)

Attempting X, old VESA xorg.conf works, though vertical offset is strange.

Attempting intel driver gets a black screen. At least the system is
responsive though!
