Kernel module (iwlwifi) - how to activate debugging?

I seem to have this exact bug with the iwlwifi on my laptop:
https://bugzilla.kernel.org/show_bug.cgi?id=60981

In the comments people are asked "to compile with CONFIG_IWLWIFI_DEBUG enabled".
Since I would like to contribute useful information to that bug report I would like to do this. I already have

$ cat /etc/modprobe.d/iwlwifi.conf
options iwlwifi debug=0xf

but thats obviously not all there is to do.

Can anyone help me with this? Do I have to compile the whole kernel and set the appropriate option in the config? Or is there a simpler/faster way of doing this?

$ zgrep CONFIG_IWLWIFI_DEBUG /proc/config.gz 
# CONFIG_IWLWIFI_DEBUG is not set

It's a kernel setting. Use ABS to set it and recompile the kernel.

Okay. I thought that maybe there was a faster way without compiling it all.
Thanks.
