Thx for the forum threads, i have changed the wiki about vt-d/iommu to reflect these new experiences.
I was hoping AMD would be able to do a better job than Intel, and have learned from the BIOS missery Intel has with there VT-d, and instruct/help the manafacturers getting their bioses right.
It's a pity that a nice feature isn't supported. No sense in upgrading my setup then to a six core and mobo with IOMMU. :(
