No, your monitor is not connected on a VGA cable, but an HDMI (or DVI)
cable through an SDVO card.
I don't see any visible differences between the two resume sequences.

I haven't heard of any trouble with resume on SVDO cards, but I also
don't know many machines using this.
Note that there's some review going on that supports hot-plug on SDVO
connected HDMI displays; it's possible that might help in your case, so
you might want to try that patch.
