If it was supported you would have seen something like this:

eth0      Scan completed :
          Cell 01 - Address: 00:0F:3D:3F:1D:CC
                    ESSID:""
                    Mode:Master
                    Encryption key:on
                    Channel:6
                    Quality:127/0  Signal level:-82 dBm  Noise
level:-209 dBm
          Cell 02 - Address: 00:0C:41:AC:F9:50
                    ESSID:"linksys"
                    Mode:Master
                    Encryption key:off
                    Channel:6
                    Quality:123/0  Signal level:-86 dBm  Noise
level:-209 dBm
          Cell 03 - Address: AA:50:23:35:5F:4E
                    ESSID:""
                    Mode:Ad-Hoc
                    Encryption key:on
                    Channel:11
                    Quality:209  Signal level:0  Noise level:47


Cell 1 and 2 are access points, Cell 3 is a computer system.  Cell 2
most likely could be used to establish a connection to the Internet with
since they don't have wep enabled and you have the ESSID.  Someone did
not configure their linksys access point.  Cell 1 appears to have
security enabled.

But again, if you are using ndiswrappers this probably won't work.
