Building up Basic Infras.

As it mentions in officia website of KGPU and CUDA,  NVIDIA GeForce 8200M is the lowest GPU that can support CUDA's features, and Linux with certian Linux kernel is tested under this project.
The following is my list:

GPU                      Cores                      Bandwidth              RAM
8200MG                 8                                 128bit                GDDR 3
9600M GT              32                               128bit                GDDR 3

Also, it mentions that it may only work under 64-bit Linux , that is

2.6.39.4 x86_64

I downloaded Ubuntu Linux and installed a few versions, just want to find out the exact same 

version of Linux kernel. As a result, Ubuntu 11.04 and 10.12 have the working version of 2.6.39.4.

Also, I made a backup of the Linux kernel for later use.

I also downloaded the open source and official NVIDIA drivers for Linux system. Here is the list:

 version 304

 version 310 test

 version 300

 version 310 beta1-ubuntu

  x.org  open source drive

I will test those drives within a few days.
