Display configuration takes a surprisingly long time on Matt's system. Looking at the code, we call update_hardware_state() in a loop, which is
a. Expensive, and
b. Isn't (or, at least, shouldn't be) necessary.

We should only need to update the hardware state once, and then grab the kernel's view of the state from there?
