Dave Russell did some testing on his X201 with various kernel versions and userspace tools. I'm attaching the results of this as a PDF.

From these results we see the following:
1) Works on Natty 2.6.38 (though a bit slower than expected)
2) Oneiric/Precise 3.0.0/3.2.0 do not work (very slow to no connection)
3) Natty with an Oneiric Network Manager (0.8.4) works.
4) Oneiric with Wicd works.
5) Oneiric with N disabled works.

So this looks to be related to network manager or could be a kernel<->userspace interaction.
