Re: That's a good point, but 64-bit Windows is not going to make this requirement go away. If you have only 4GB of memory installed, the video device will still grab a section of this for MMIO. The benefit will not be realized until one moves to >4GB of memory.

Wrong. That's not how it works. When you have a flat physical address space of a terabyte, you just map the devices like video cards and ports to starting addresses of, something like 256GB. Ram addresses from 0 to 4GB can stay just that - the hardware moves easily out of the way.
