Asus P6t VT-D support

[Enforcer]

I have a asus p6t motherboard (link to bios: https://dlcdnets.asus.com/pub/ASUS/mb/LG...S-1408.zip)
When I enable VT-D, windows refuses to boot and qubes warns that it wont install properly if I try. Apparently this is an issue with the DMAR table. My CPU is core i7-920. The wikipedia page for VT-D compatibility says that this CPU should support it. However that isnt the case so far. Can someone mod this BIOS to support VT-D in actuality instead of just in the manual?

I would like to piggy back on this request. Have a P6T SE and VT-d is gone with BIOS 0908 

Also, the optical audio seems to be gone as well... but that's just a side issue.

The oldest BIOS revision that I managed to test was 1004 (the motherboard wouldn't let me install a BIOS older than itself) and I also tested everything in between. None of them brought a positive result. If that's of any help.

It's weird, because the version you list is 1408 and it appears to be for P6T. My board is P6T SE (to be exact) and the BIOS on ASUS's website for that particular board is at 0908.
