Unresolved symbol!

Hello!!
I have some problems after installing fglrx!
This is the output error after typing modprobe command:

If someone would be so kind to help me ;) I give him some other infos:

I am running Debian stable version with 2.4.27 kernel
I've done those step to install drivers:

1. reconfigured kernel options in according of paragraph 2.1.1 (config file
in boot dir)
2. cd /usr/src
    tar xjvf kernel-source-...
    cd kernel-source-...
    cp boot/configFile .config
    make-kpkg --append-to-version .......
3. Got XFree86 4.3.0 binary packages (I have XFree86 4.3.0.1 version)
4. Installed bin packages using dpkg -i command
5. unpacked module sources using bzcat....
6. built modules using module-assistant
7. prompted modprobe -v fglrx and got the error message

It will be a stupid problem...but I'm a Linux newbie :)
thanx!!!!!!!!!

bye, andrea
