Unfortunately not. Adding a feature like that is a major change. Even a full base layer respin, i.e. C-0 to D-0, would probably not be enough to add a feature like that. It would require a whole new version of the chipset. This C-0 to C-1 transition is a relatively minor metal layer revision. They could probably enable the originally planned features that were disabled, but still present in silicon. These would include additional SATA 6GB/s ports, and possibly SAS connectivity. USB 3.0 was never planned for the X79 chipset, and is not (as far as we know) present in silicon.

VT-d is a virtualization related instruction set. It's only real use is when you are using a program to run a guest operating system within your main operating system. This is mainly done in servers to consolidate operating systems dedicated to many different tasks onto a single machine. VT-d is an instruction set that improves the interaction between a virtualized guest operating system and the peripherals of the host computer.
It has nothing to do with gaming performance on a regular gaming computer. The only time it would improve performance would be for gaming inside a virtualized OS. Virtually no-one is going to be doing this, as performance would still be inferior to that achievable by running the game on the native OS.
