Oh, that's a good point. Doing things in this order essentially forces yet another full panel power sequence delay at this point. Hrm. I'll have to test again when I get a chance, but perhaps we can turn the sink DPMS on before we turn the panel power off.

Right, I'll try doing the sink_dpms before turning the panel off; that should work just fine, and should make the sequence a bit faster.
