求助高手：fedora11中驱动程序安装问题

我的显卡是ATi Radeon 9250，装的是fedora11系统，下载了.run格式的驱动程序文件后，在终端中安装时出问题，错误提示：
==================================================
ATI Technologies Linux Driver Installer/Packager
==================================================
which: no XFree86 in (/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/yincu/bin)

Error: ./default_policy.sh does not support version
default:v2:i686:lib::none:2.6.29.4-167.fc11.i686.PAE; make sure that the version is being
correctly set by --iscurrentdistro

Removing temporary directory: fglrx-install.NI0HKd

怎么回事呢？上面说XFree86不在一些文件夹中，什么问题呢？要重新安装XFree86？
