One more question; does the driver work with wpa_supplicant for WPA, or
does the firmware capture the EAPOL frames and handle the 4 way
handshake internally?  Ideally the firmware would have the ability to
pass those frames up unmodified so the driver would at least have a
_hope_ of 802.1x capability.  Does the firmware handle Dynamic WEP at
all?

Basically, what happens when the AP you've just associated with starts
sending you EAPOL traffic to start the 802.1x process?

The PS3 wireless device does the association and 4way handshake in its
firmware/hypervisor.  No interventions between them are allowed to the guest
OSes.  
All frames which are sent/received from/to before the connection process
completed seems to be dropped by the hardware.  Only the static WEP is
supported.

That sort of sucks; but I guess there's not too much you can do about
it.  That probably means that using wpa_supplicant + WPA is completely
out of the picture, which unfortunately makes the PS3 wireless unlike
any other card, which would require special-casing the PS3 in userspace
tools.
