If you just want to remove the module from system but not to delete forever
turn off wifi
open a root shell
run: rmmod cw1200_wlan.ko
The files you mention exist on my phone in the following folders: /system/lib/modules/3.0.8+/kernel/net/compat-wireless/drivers/staging/cw1200 and /lib/modules.
I'm unable to delete/rename them even when using root.
The error message I get is "Read-only file system".
If I use "rmmod" as you mention, how can I undo this operation?
