unresolved symbols - change_page_attr

[Borondil <borondil at atlas dot cz>]

Hi,
I am tryin to get a radeon 9200 going. I'm using Debian Woody, so I 
tried the packages for xfree-4.1.0. But when I compile the kernel 
module, I get this:

jirka at debhome:/usr/src/kernel-source-2.4.18$ sudo fakeroot make-kpkg 
--added-modules=fglrx-4.1.0-3.9.0 modules_image
...
ATI module generator V 2.0

...

and then

jirka at debhome:/usr/src$ sudo depmod -ae
depmod: *** Unresolved symbols in /lib/modules/2.4.18/misc/fglrx.o
depmod:         change_page_attr

and

jirka at debhome:/usr/src$ sudo modprobe fglrx
/lib/modules/2.4.18/misc/fglrx.o: unresolved symbol change_page_attr
/lib/modules/2.4.18/misc/fglrx.o:
Hint: You are trying to load a module without a GPL compatible license

/lib/modules/2.4.18/misc/fglrx.o: insmod 
/lib/modules/2.4.18/misc/fglrx.o failed
/lib/modules/2.4.18/misc/fglrx.o: insmod fglrx failed

As you can see, I'm running the 2.4.18 kernel and xfree-4.1.0. Is an 
upgrade necessary?

Any help would be appreciated.
