Tested the latest version on the Acer c720, HDMI works now, not only
video, but also audio (which is great).

There were a couple of red lines in the left upper corner of the
screen (which disappeared eventually):

Also had the problem of wrong permissions/group on /dev/dri/* another
user reported earlier.

chrome reports that MESA-LOADER doesn't recognize the PCI ID.

Suspend/resume doesn't work (machine boots on resume). When setting
sysctl debug.acpi.suspend_bound=1, the screen stays off until the
graphics mode is changed (e.g. start X). It shows the following message
at the console:

error: [drm:pid687:i915_write8] *ERROR* Unknown unclaimed register
before writing to 3b4
error: [drm:pid687:i915_write32] *ERROR* Unclaimed write to 70030
info: [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

Thanks for working on this!
