笔者使用的是华恒公司提供的基于at91rm9200的开发板，公司提供的开发环境使用Linux内核是2.4, 交叉编译环境也比较老，由于笔者用到的驱动对2.4内核支持不好（尤其在arm上）。笔者决定自己移植2.6内核到该款开发板上，目前工作已经基本完成。 本部分介绍了几个驱动程序的移植过程，特别是显卡部分。-author used the huaheng company based at91rm9200 development boards, provide development environment is the use of Linux kernel 2.4, cross-compiler environment is also a veteran, As I drive right to use the 2.4 kernel support well (especially in the arm.). I decided to transplant themselves to the 2.6 kernel development board which, at present the work has been basically completed. This section presents a few of the transplant procedure-driven process, in particular the graphics part.
