[Regression] [PATCH] intel_crt_detect_ddc() seems to be broken for DVI-I

["David Müller (ELSOFT AG)"]

Hello

Since Linux 2.6.36 the digital output on my system (855GME + DVI-I) is
not working any longer. The analog output is always activated regardless
of the type of monitor attached.

The culprit seems to be intel_crt_detect_ddc(), which returns true as
soon as an ACK from the EDID device is received. Obviously this approach
does not work with DVI-I where the analog and digital outputs share a
common DDC bus.

The patch below adds an additional check to make sure that there is
really an analog device attached (similar to the "Mac mini hack" in
intel_sdvo.c)
