Hey rubin110!

Thanks for the incredibly detailed instructions! (Stashing those away for the
future!)

I'm compiling the new kernel as I write this, once it's done I'll reboot and
start testing.

The answer is YES! I actually drive my dual screens (3x Dell U2713HM) using
this docking station:

Using both of the DP connectors.
