Bug Description
I have a DisplayPort with a passive DVI adapter plugged into it to run my DVI monitor. However the i915 module seems to want to call this connection "HDMI1".
Call it DisplayPort or DVI. Either would be correct. But HDMI is wrong.
This occurs on Ubuntu 11.04 and 11.10beta2.

DP1 disconnected (normal left inverted right x axis y axis)
This is probably because the DisplayPort is running in DVI/HDMI mode [http://
But it's still wrong to call a DVI connection through DisplayPort "HDMI".
This bug might be caused by the fix for bug 702125.

I've now tested mainline kernels 3.1 and 3.2-rc1. This but is still not fixed in either.
