yes

Using DMA for GR commands and all data transfers will be a lot faster and
more efficient
The driver fully utilizes the NV architecture I will be doing the 3D OpenGl
part and VIDEO in

Also it works in a completely deferent way
The client (NVXF) sends commands to the NV chip thou channel's DMA or PIO
these
Channel are allocated by the kernel module amd are protected by the NV chip
its self
So a local error will not bring down the whole system
Also functions like sleep process until commands is are finished using
NOTIFY can be used
Grate for compatibility, as the client only needs to concern its self with
NV commands and not the chip IO so NVXF for NV04 will work on a NV15

And it is something I really won't to do :)
