Directly rendering graphics to the kernel through xorg?

I heard this from somewhere a while back in a windows vs linux debate, so I consider it a rumor, but I wanted to clear it up. 

The windows guys were saying that their UI is snappier because their OS renders graphics directly to the kernel.  With linux, it has to go through xorg first, creating a bottleneck.  The linux guys came back and mentioned that there are patches to enable this capability.

Is this total bs or is this real?

I don't know about xorg, but there was fbui: http://home.comcast.net/~fbui

Don't know if it works again. Also kernel based modesetting might be of interest to you: http://www.rootly.com/topics/technology … deSetting/

It's unusable, try directfb instead.
