rmmod kernel module problem

Lately I follow kernel module programming guide on
I'd successfully "insmod ./hello.ko" kernel modules; and could see it in /proc/modules.
However, when I want to unload the module with command "rmmod hello".
It issues error "FATAL: Kernel does not have unload support". But I cant see rmmod located in /sbin.
Further, if issued with command "/sbin/rmmod hello", it has error printed as "rmmod: QM_MODULES: Function not implemented".
Where did I do it worng? I appreciate any suggestion.
thank you very much.
p.s.: I use debian 3.0 r2 with knernel mannually updated to 2.6.9 [Additionally, I don't not find any default module stayed at /lib/modules/2.6.9/, except old one when installed 2.2 kernel version. Is that correct?]

You have to configure your kernel to unload modules in this section...

# Loadable module support
# CONFIG_MODULE_UNLOAD is not set <-----here
