I think the message goes wrong already at the beginning, "hardware
requires preliminary hardware support". The hardware really requires
full support, but preliminary is all we've got so far, and that's been
disabled by default...
How about something along the lines of,
"""
This kernel version does not properly support the hardware.
Preliminary support disabled by default.
See CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT or i915.preliminary_hw_support.
"""
