How Linux handles video acceleration? Is there a standard?
If I want to use the driver /dev/nvidia0, how can I make?

I'm not really sure, but I think you may be looking for
this.
I know next to nothing, so I'm just as curious as you.

Note regarding Mr. Man's link: Last I checked nVidia's closed source drivers did not use DRI.
Neither nVidia not ATI release specifications for their graphics cards. Furthermore the 3D accelerated drivers are closed source. This makes /dev/nvidia0 unusable other than through the closed source GLX driver.
That said, there is some information available.
- http://wiki.x.org/wiki/nv - Describes the MIT licensed nv driver for nvidia cards. However, this driver has no 3D acceleration.
- http://nouveau.freedesktop.org/wiki/ - Is a project aiming to producing Open Source 3D drivers for nVidia cards. The "Documentation" section seems to have some information available.

It puzzled me lot , too. But as a further learning I found something no more than DRI. Maybe it will be helpful.
By the way, Intel has opened the source of his Graphics chipset . That's a great news.
