 *	- WB : write back stuff (do it bit like scratch reg things)

 *	- Vblank : look at Jesse's rework and what we should do

 *	- r600/r700: gart & cp

 *	- cs : clean cs ioctl use bitmap & things like that.

/* Initialization path:

 *  We expect that acceleration initialization might fail for various

 *  reasons even thought we work hard to make it works on most

 *  configurations. In order to still have a working userspace in such

 *  situation the init path must succeed up to the memory controller

 *  initialization point. Failure before this point are considered as

 *  fatal error. Here is the init callchain :

 *      radeon_device_init  perform common structure, mutex initialization

 *      asic_init           setup the GPU memory layout and perform all

 *                          one time initialization (failure in this

 *                          function are considered fatal)

 *      asic_startup        setup the GPU acceleration, in order to

 *                          follow guideline the first thing this

 *                          function should do is setting the GPU

 *                          memory controller (only MC setup failure

 *                          are considered as fatal)
