I have a T60P laptop and I am trying to get Server 2008 Hyper-V installed and working on it.
I set the virtualization Technology to enabled in the bios (version 2.23) and when I tried to start hyper-v it failed. I found out that you need execute disable bit enabled also. The problem is as soon as I enable that, it disables the virtualization technology through the software. What I see is that they are both enabled in the bios, but the Intel Processor Identification Utility shows the virtualization techology as No. If I disable Execute disable bit, then it shows virtualization technology as yes.

I have no experience with Server 2008 Hyper-V, but do have some with the similar VMware. In the course of setting that up I came across the following links:
The bottom line seems to be that hardware VT may actually reduce performance on Core Duo, which does not support EM64T. VMware disables hardware VT in software for this reason; it seems likely that Server 2008 Hyper-V does the same. So I don't think it's a BIOS / chipset bug.
