The hypervisor interface for the wireless connection of PS3 is the steps
as follows:

1) The guest OS (driver) asks the hypervisor to collect AP information
(scanning list) and return it
2) The guest OS tells the cipher information, i.e. cipher algorithm
WEP/TKIP/CCMP and its keys, to the hypervisor
3) The guest OS selects one of APs which are returned by the hypervisor
and tells the index of the list to the hypervisor 
4) The hypervisor (and wireless firmware) tries to connect the AP
specified in the step 3) and the hypervisor returns the result of the
try.

Thus the old driver also should _select_ an AP from the scanned list.

The difference between the old and new drivers is the rule of the selection. 
The old driver just selects the first AP of the list if specified essid
is not found in the list.  As the hypervisor sorts the list according to
the radio signal strength, the old driver would try to connect to other
AP if more powerfull AP appears in your building, I think.

Yes.  A patch is needed.

Not yet.

I'll send it to you in another mail.
