Blfs 安装ati显卡驱动的问题

笔记本显卡是hd2400xt ,刚刚做了lfs6.3，blfs也装好了xorg7.2和kde3.5.9。现在用的是vesa驱动。
从ati 官网下了新的驱动，
sh ati*.run安装出错
/usr/share/ati/fglrx-install.log信息如下：
[Message] Kernel Module: Trying to install a precompiled kernel module.
[Message] Kernel Module: Precompiled kernel moudile version mismatched.
[Error] Kernel Module: No kernel module build environment - please consult readme.

我已经解压了内核的源码到/usr/src/，gcc，make做LFS都正常，应该不能有问题。
这个kernel module build enviroment到底是什么东西啊？
请达人指惑。

1. sure your kernel option selected:
Bus options (PCI etc.) --->[*] Enable deprecated pci_find_* API (example for 2.6.27 kernel, previous kernels are similar with it)
2. then patch for ATI driver or kernel

LFS 6.3 用的是2.6.22.5 内核，在BUS Option 里没找到您说的那项，
必须要升级内核？

forgot 2.6.22 kernel case, seems it needn't be considered. includes 2.6.26 or later version should be done.
which ATI driver version did you select? later 8.10 should be not problem. don't need patch for it.
if you want to select the new kernel, 8.12 version can be done for 2.6.27 kernel.

thank you for your help.
I will take your advice and upgrade my kernel to 2.6.27.
