I don't think 128-bit is coming any time soon, at least to the consumer space. What would require a larger address space than 17.2 billion gigabytes? Any ideas?
It would make sense that 128-bit compatibility would be built into the kernel for both server and desktop OSs.
Since MS has been using (essentially) a unified kernel architecture since XP/2003 (XP and 2003 share a kernel, Vista and 2008 share a kernel, 7 and 2008R2 share a kernel), it's been on the front-end user experience and back-end processes where the server and desktop OSs have differentiated themselves.
At 128-bit, encryption and compression operations would be super-massive-insaneo-fast, as well.
Well, let's see... 128-bit is the key size for many of today's popular encryption algorithms, it can process quadruple-precision float/int (big deal for science). Those are the big two.
We are just getting 64 bit to be widely accepted, and now they want 128 bit. Some people (like software engineers) are just never happy with what they've got.......
Whether or not 128-bit is used or accepted 5 years from now, I think its a good move and proper planning. Besides I rather have an OS planned with 128-bit support rather than an afterthought.
Cloud enviroments may require this- or at least Exchange 2015 will. Jerks!

Also, can/do graphics cards do this kind of work currently?

Being happy with what you have right now doesn't exactly fuel innovation.
