algorithm like WEP. IEEE 802.1X is authentication protocol which can be
used with IEEE 802.1X EAPOL-Key frames to distribute WEP keys _or_ with
WPA to generate keying material for WPA 4-Way Handshake that will
generate the data encryption keys.
Yes, sorry, what I was trying to distinguish was using WPA using either
PSK or 802.1x for 4-way handshake. I did not know there were two 802.1x key
mechanisms though, as you point out. Wherever I said just TKIP I meant over TKIP
using a PSK. I believe the second mode of 802.1x can be used with this
chipset, not sure of the first though (to distribute WEP keys).
I kind of though so, too, but the configuration did not match this at
all.. WPA-PSK and WPA-EAP(IEEE 802.1X/RADIUS) should use the same
settings for IEEE 802.11 auth alg and MLME auto level.

DOT11_AUTHENABLE should be set to DOT11_AUTH_OS for WPA modes (i.e., not
_SK or _BOTH like you had in some cases). DOT11_AUTH_SK can only be used
with static WEP configuration (i.e., not with WPA or with IEEE 802.1X
when using dynamic WEP key generation). DOT11_AUTH_BOTH is likewise only
reasonable for static WEP configuration since it includes _SK as an
option. 
OS stands for Open System here. Are you sure of this? I'll ask around, just to
confirm too.
Yes, I'm sure. See IEEE 802.11 standard for details. Open System auth
alg is required for WPA. Shared keys auth alg uses WEP, so the only to
use it is to have pre-shared WEP keys. I don't remember whether FullMAC
version of PrismGT driver has a separate mode for WPA, but if not, this
oid needs to be OS. It certainly cannot be SK.
