It is hidden by "choice" with interesting name.

Unfrotunately, if I do this, I get kernel messages for about a second,
and then blank screen. Thinkpad X60...

I now have:

i915.modeset=1 video=inteldrmfb:mode=1024x768 fbcon=scrollback:64k 

on cmdline and:

CONFIG_DRM=y
CONFIG_DRM_KMS_HELPER=y

# CONFIG_DRM_R128 is not set
# CONFIG_DRM_RADEON is not set

Perhaps something like this should be done? I had no idea that the
choice is for modern drivers, too...
