I've got the following answer from Biostar in respect to the Biostar
TA890FXE main board.

The motherboard supports IOMMU, but the CPU you are installing also must
support IOMMU.

I've just took the risk to order this mainboard as the main board is
relatively cheap and I hope/presume the IOMMU will be supported
eventually if it's not supported yet.
I'll update you when I know the result.
I understood IOMMU is not related to the CPU i.e. IOMMU should also be
supported when the CPU on the main board is a AMD Phenom II X2 550 Black
Edition?
