The chipsets supporting VT-d, are "Bearlake" and "Seaburg".  To my knowledge the -B -G and -X refer to various supported SKU options available for the Bearlake, including cache and cpu cores (ex. dual vs quad).

Bearlake and Seaburg are north bridges in the platform, they handle the DMA remapping capability within the chipset (see the VT-d public specifcation etc.).  The suffix is more about the SKU fusing than the fundamental chipset capabilities.

Enabling the chipset in BIOS does not guarantee the kernel/OS/VMM is properly configured/compiled to support it.

Xen 3.2 final (released last week) has support for VT-d and tboot (trusted boot).
