How can I find the driver's debug message?

Hi, there.
I'm using Fedora Core 4, Samsung magiclan 2100N and linux-wlan-ng-0.2.3.
The installing was successful.
But, I want to watch the debug log, so I set up some variables.
While 'make config', 'Build for debudding?' is 'y'.
And I added this line at the end of the '/etc/pcmcia/config.opts' file,
module "prism2_cs" opts "prism2_debug=5"
and I added this line at the end of the '/etc/modprobe.conf' file,
options p802.11 wlan_debug=5

But there nothing in the '/var/log/messages' file.
Sometimes, 
Apr  6 17:26:44 localhost kernel: linkstatus=DISCONNECTED (unhandled)
Apr  6 17:26:45 localhost kernel: linkstatus=CONNECTED

It's all!
How can I find the driver's real debug messages?
What should I do?
Please Help me~!
