I dont know if virtual pc can even run Linux, it would be a odd choice for Microsoft.
Vmware is much more better in virtualization.
So if you really want a virtual Suse running in your windows, why dont you just download vmware player (ITS FREE) http://www.vmware.com/products/player/
After that all you need to do is to download the pre-built image of suse :
That is a Suse 10.0 with KDE
There are also many other FREE and pre-built images around.
