Excellent.

OK, so if we have a pure single link DVI/HDMI for the HSW it seems we're doing
the right thing. It's just more a matter of luck that the single link also
works for these high resolutions which according to the EDID should require
dual link.

I guess I'll just mark this as a NOTABUG because everything seems to work as
intended.
