Intel's hexa-core Core i7-3960X (3.3 GHz) and Core i7-3930K (3.2 GHz) will be getting a C2 revision in January to fix Intel VT-d support.
As reported earlier, Intel's first wave of Sandy Bridge-E processors have VT-d (Intel Virtualization Technology for Directed I/O) disabled due to an errata in the C1 stepping. That issue couldn't be resolved in time for the launch but it's getting fixed with the C2 stepping which is set to start rolling out to customers on January 20th, 2012 (samples have already been delivered).
