Perhaps you should tell this asrock. Today I got an answer from asrock 
support:

<asrock-support>
Sorry for lat reply. Taiwan was still checking this issue. And they told us:

Again IOMMU also need CPU to support.
Till now, AMD has no plan to support IOMMU on desktop CPU (AM3 socket).
Also "IOMMU" not list on our 890FX Deluxe3 specification
Please 890FX Deluxe3 link:
http://www.asrock.com/mb/overview.asp?Model=890FX%20Deluxe3

In feature, AMD release that CPU, we will borrow it, and test it.
Any news will update to you.
Thanks your mail.

Best regards,


ASRock Support
