I've tested this build with the following on my Thinkpad T420:
1) Plugged in VGA cable to external monitor, waited monitors to set proper resolution.
2) Unplugged VGA cable, waited for LVDS1 to be set to proper resolution.
3) Repeated 1/2 a few times.
4) Suspended and resumed.
5) Repeated 1/2 a few times.
This works for me. If somebody else can confirm, I'll get this applied to raring, and SRUed to other series.
