Hi,

I actually wanted to send a patch for at least find out a bit more about it,
but my laptop broke so I will have to get it repaired first.
Anyway if someone wants to work on this meanwhile: 
The key settings (dumped from ndiswrapper) for ie_dot11WEPDefaultKey struct 
seem to be 

setting key 0, len 32
cmd_type 0x000c, cmd_status 0x0000 [Idle]
action 1 keySize 32 type 11 index 3 defaultKeyNum 0
setting key 2, len 32
cmd_type 0x000c, cmd_status 0x0000 [Idle]
action 1 keySize 32 type 10 index 3 defaultKeyNum 2
setting key 1, len 32
cmd_type 0x000c, cmd_status 0x0000 [Idle]
action 1 keySize 32 type 10 index 3 defaultKeyNum 1

You also need to change the wpa_supplicant supplied key to match the ndis 
spec:

		/* wpa_supplicant gives us the Michael MIC RX/TX keys in
		 * different order than NDIS spec, so swap the order here. */
		memcpy(ndis_key.key, key, 16);
		memcpy(ndis_key.key + 16, key + 24, 8);
		memcpy(ndis_key.key + 24, key + 16, 8);







No idea what is need otherwise, apart from writting a wpa_supplicant driver 
and fixing the scan ioctl.

Regards,

Sascha
