hello all,
don't bother on this message if you feel it has nothing to be here.
But I rencently read a whole lot of MSDN documentation about the LDDM
infrastructure. The new Windows graphics vista driver model.

And what made me think we could have support for it in linux.

It seem to me that having the most important parts of the driver
being in user mode would really help to use it on other systems.
Sure there would be need to have a PE loader and some kernel
module support, but from what I read, the user mode driver would
create the command buffer that would need to be uploaded to the
GPU and the kernel module would need to schedule GPU access handle
memory of the GPU and send the command buffer to it.
I'm aware this could interest more the Wine mailing list,
but maybe the struggle to have linux specific support from Graphics
adapter vendors could be one for all removed if we had LDDM driver
support and then and X build on top of it (same philosofy as Xgl).
sorry if it sound crazy...
