I will test it as soon as I can.

While it does seem to flicker more with the angle of the lid, there is no
flicker whatsoever with Windows or with the framebuffer driver (I remove the
i915.ko file and reboot), so it is not exclusively a hardware issue.  The
hardware works without flicker with other drivers.

I have no chance of getting any kind of support for this issue on this
computer, as there is no problem with windows.  For the vendor the computer
works.  With the linux driver it doesn't (at least until now).
