Fedora 3中Xfbdev的设置问题，请各位帮忙

ygl_0724

我用Xfree864.2.1编译生成了Xfbdev,然后在Fedora Core 3运行。
内核 2.6.9
我的实现步骤如下：
1 修改/usr/X11R6/bin/X链接
  rm -f X
  ln -snf /usr/X11R6/bin/Xfbdev X
2 修改/etc/grub.conf：加了vga=0x314
3 修改/etx/X11/Xorg.conf（更改了部分如下所表示）
  Section "Device"
        Identifier  "Videocard0"
        Driver      "i810"
        VendorName  "Videocard vendor"
        BoardName   "Intel 915"
   EndSection

  Section "Device"
        Identifier  "framebuffer"
        Driver      "fbdev"
        VendorName  "Videocard vendor"
        BoardName   "Intel 915"
  EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "framebuffer"
        Monitor    "Monitor0"
        DefaultDepth     16
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes     "default"
        EndSubSection
EndSection
4 重启机器

出现的效果如下：
　　其它服务能够正常启动，但启动X的时候，出问题了。系统弹出一个文本类型的对话框，说不能启动X Server,配置不正确。但是可以回到字符界面。我用root登录后，敲入startx，X能够启动。但是我换到普通用户时，startx就不好用了，系统提示只用超级用户才能启动X。我每次重起都是上面的效果。

不知道问题出在哪？还请各位多多指教!
