it's well possible that kwm just throws away the extra bits - here's what's
in the code:

#define DCT_WEP_KEY_FIELD_LENGTH 16
...                                   
struct tfd_data {
...
        /* Tx Parameters */
...
        u8 wepkey[DCT_WEP_KEY_FIELD_LENGTH];

which, if I read it correctly, means that wepkey's size is 8 x 16 = 128bits.
So 256bits keys simply won't fit.
That's from 

#define IPW2200_VERSION "1.1.2"

Of course, I may be wrong, or there are ways to combine&use 2keys at once...
