I have this card too. Under Karmic I were able to load the wifi by using "rfkill unblock wifi". Now I updated to lucid amd64. I don't have the option to start the wfi in the networ-manager anymore.
iwconfig is giving me: wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off and lspci is giving me: 04:09.0 Network controller: RaLink RT2561/RT61 rev B 802.11g rfkill unblock wifi doesn't work anymore.
