The plot thickens: ubuntu's 2.6.38 kernel with ubuntu 11.04's
userspace works. But the same 2.6.38 on 11.10 userspace does not work.
So your report on 2.6.34 is most likely accurate. Somehow userspace is
what it is triggering the problem.

IIRC, 2.6.34 is the first version with the updated driver. After that,
there are only unimportant interface changes to keep up with the rest
of the kernel. So 2.6.34 should work as well as 2.6.38 or even 3.0.

Hmm, maybe I should try 2.6.32 on the 11.10 userspace and see what happens.
