[Grml] ipw2200 monitor mode

hi,

i have grml@hd, ipw2200 modules -1.0.8 with linux-headers-2.6.16-grml, so i think it's grml 0.7 and don't know witch driverversion...

and monitor mode doesn't work:

# iwconfig eth0 mode monitor Error for wireless request "Set Mode" (8B06) : SET failed on device eth0 ; Invalid argument.

please, does anyone know how to get working this?

thanks, markus.
