Hi Simon, this acceleration scheme called my attention.

The goal of my GSoC project is to decrease the latency of the cursor 
inside X server. What I'm pondering right now is how we can shortcut the 
path between the input and the hw cursor rendering -- which is already 
done inside DRM modesetting. This all will impact in the acceleration 
code [0] which would need to be done inside the kernel as well. However 
this is all in the ideal world where all drivers have their counterpart 
inside kernel...



Thank you,

[0] beside the accel, I'll have to deal with input transformation, the 
cursor limits, etc.
