Oh wow, that's super low. I've noticed that some Intel CPUs with the "U" suffix (meaning ultralow voltage, minimal power draw and heat generation but also minimized performance) will run slower than what Intel suggests is the minimum. Not sure about how this works really.
Try googling for the "Dolphin Emu Laptop Performance Guide" and in that thread read up about using Throttlestop. The GPU part of the guide will also help you with that "failed to enumerate outputs" error and hopefully let you use D3D. Be warned that you may still run into performance issues even when Throttlestop works, simply because your CPU is slow even when it's at its best.
