VT-d support on P5E-WS-PRO

Anyone know if VT-d is enabled in any BIOS releases on the P5E-WS-PRO board?

In the manual for the motherboard, there is a "Vanterpool"
setting. (In the "CPU Configuration" BIOS screen, section 4.5.1)
But you're asking for another level of refinement, mentioned here.

http://en.wikipedia.org/wiki/VT-d#Intel_VT_.28IVT.29

"Intel plans to add a technology named Virtualization for Directed I/O
(VT-d) to VT. This provides a way of configuring interrupt delivery to
individual virtual machines and an IOMMU for preventing a virtual
machine from using DMA to break isolation."

You can download the X38 datasheet here, which is your Northbridge.

On PDF page 94, VT-d is a Read-Only attribute, and is Enabled.

48 RO 0b VT-d Disable (VTDD):
0 = Enable VT-d
1 = Disable VT-d

So it would appear from that, to be enabled. I suppose there could be
a bitfield somewhere else, that overrides it. You'd need more documentation
from somewhere, to understand what hardware components are needed to support
it. (Like, where or what is used for the IOMMU ?)
