I just installed Ubuntu 10.04.1 LTS on an out of the box Thinkpad x201 with the following wireless card: Intel Corporation WiMAX/WiFi Link 6050 Series. Wireless would not work out of the box.
I installed the 2.6.32-25-generic and can confirm that linux-backports-modules-2.6.32 fixed the wifi issue on my x201.
