I'm not looking to address software cursors, right now I'm only
interested in the hardware one.

If this is going to be a separate spec we need to start it immediately
since the current Xgl implementation assumes the existence of a
hardware cursor. I can make Xgl directly access the fbdev hardware
cursor support but I would much rather use an EGL version.

How is EGL going to get a bitmap into the cursor? Use OpenGL command
to create the surface and then pass it into the cursor create function
which will copy it? Since I already have the working fbdev
implementation it is pretty easy to implement cursor support as soon
as we come up with an API.
