Mine is attached, unfortunately the only interesting difference seems to
be the Base board serial number:
-	Serial Number: /sku
+	Serial Number: XXXXXXXX

But given we both have an ID12 that's most likely not very relevant (or
maybe different bios versions do different amounts of setup on the hdmi
bridge).

Even though i did some attempts i've never seen the hdmi output work in
linux (and didn't know it was attached to LVDS). John did mention it
only works up to 720p, so it could very well be i simply never send it a
mode it actually supports.

Reverting this patch will cause a regression in that the higher levels,
e.g. X, always thinks there is an output on the LVDS port so it comes up
in a very odd mode (but at least one can work around that with
configuration), so i guess the patch should be reverted :/

Ideally we'd find a way to do hotplug detection on the lvds-to-hdmi
bridge (any ideas where to look for that would be much appreciated).
