The ip_wccp module linked from the Squid FAQ works with any Linux-2.4
release.

You can only have one installed at a time.

You can select if you want to use the WCCP-specific ip_wccp module, or
a patched gre module with support for WCCP added.

What have you tried, and what error do you get.

A almost fail-safe method of building the ip_wccp module is to

1. Build and install your own kernel. Take note what the gcc lines
typically look like while running "make modules".

2. Reboot into this new kernel to verify that it works fine before
continuing.

3. Compile the ip_wccp module using a command line which looks a lot
like the line noted in step '1' above, but specifying the ip_wccp.c
module instead of the other module which the line was for.

3. Install the resulting ip_wccp.o module in
/lib/modules/<kernelversion>/net/

4. Run "depmod -a".

5. Run "modprobe ip_wccp" to load the ip_wccp module.
