newbie kernel module load problem

[Michael Minnick <mminnick@Aureal.com>]

I've compiled my first kernel module, and when I try to load it I get
the following:

# insmod hello.o
hello.o: kernel-module version mismatch
    hello.o was compiled for kernel version 2.0.36
    while this kernel is version 2.0.34

How can I either upgrade the kernel to 2.0.36 or compile for 2.0.34?
I've download and installed the debian package for kernel-source-2.0.34
and it has a link to in in /usr/src/linux, but somehow I seem to be
compiling for 2.0.36.

Thanks,
Mike
