Vista - Hyper-V Integration components in WIN PE

We use SCCM 2007 OSD to deploy Vista and 2008 images. During the deployment
there are several menu questions you answer in a WINPE enviornment. SCCM
uses PE based boot images with some HTA menu systems.

When dropping an image to a Hyper-V session the performance is terrible.
The performance should be much better and upon further inspection we believe
it could have something to do with they missing integration components. We
have seen some articles out there,

On how to add the integration components to PE. I am wondering if anyone
has tried this or if this could be what are problem is?
Essentialy when deploying images to the hyper-v enviornment and are in the
PE it takes a very long time for the HTA menus to display and process.
Normally these only take seconds when you deploy to stragight hardware.
