Hyper-V Server 2008 R2 on Asus M2N-LR with AMD Opteron 1218

Has anyone been able to run a virtual machine on a Hyper-V Server 2008 R2 installed on an Asus M2N-LR motherboard with an AMD Opteron 1218 processor?

I can run Windows 7 x64 with Virtual PC running Virtual Windows XP.

I get the same results as Greg Shultz in his article: http://blogs.techrepublic.com.com/window-on-windows/?p=1278

Thanks.
