Core 2 E4300 can run Virtual PC but XPM not supported?!

My CPU is Intel Core 2 E4300. I have been running Windows 7 x64 and have installed Microsoft Virtual Machine 64 bit edition.
I have 3 Windows XP machines inside Virtual PC 2007 SP1, and all of them runs fine.

I was reading the thread regarding the CPUs that supports XPM, and E4300 is listed as NOT supported.
Is it possible??? I can run my own WinXP virtual machines, but I cannot run XPM?

After I installed Windows Virtual PC Beta x64 (Windows6.1-KB958559-x64.msu) and Windown XP Mode Beta (VirtualWindowsXP.msi), I can NO longer run my Virtual PC 2007 program.
The error message was "Virtual PC 2007 SP1 is not supported on this version of windows".
This is weird.

Also, where can I find a tutorial on setting up XPM step by step?

Thanks

Correct.
