Frank,
 
Thank you for these precisions.  We'll look at how VIP is implemented
in Radeon and see if we can learn from it.
 
Did you say that GX2 also has VIP capabilities or is this only
applicable to the LX?

So from my understanding, it can be seen as an individual module that has relationship with geode graphics driver. And It will use PutImage function to do the overlay like what Radeon does in this part. And from the Jordan's log, I can not find anymore information that is useful to prove my point.

That is why I asked the question. It looked to me that VIP is a feature of the driver rather than a separate driver. Without hardware to test, it would not be safe to make that change. 

[Frank] Yes, I agree with your point. It is better there is a board to develop this part driver to do the change.
