I was not aware of this new Linear Allocator. Are there any docs on how 
to interface this into the drivers at all? I would like to take a look at 
it and see how it works. We would like to be able to hook the linear 
allocator functions such that we can do surface management in offscreen 
memory ourselves in our driver. Is that possible with the linear 
allocator (ie: hook out the functions that create the surfaces somehow)?

Also is using the linear allocator a requirement for Xv?
