问题一：以前安装时好象inte-agp和agpgart自动就安装了，现在的情况是
intel-agp没有自动安装，agpgart在模块中找不到！
Linux:~# modprobe -l | grep agp
/lib/modules/2.6.18-4-amd64/kernel/drivers/char/agp/sis-agp.ko
/lib/modules/2.6.18-4-amd64/kernel/drivers/char/agp/via-agp.ko
/lib/modules/2.6.18-4-amd64/kernel/drivers/char/agp/intel-agp.ko
Linux:~#
没有显示agpgart模块！

问题二：显示分辨率只能上到1024x768@75  (Dell的液晶显示器)
无法上到1280x1024@75

问题三：glxgear的输出正常吗？
Linux:~# glxgears -printfps
1370 frames in 5.3 seconds = 258.703 FPS
1320 frames in 5.3 seconds = 250.750 FPS
1320 frames in 5.3 seconds = 250.801 FPS
