It looks like this needs a newer version of the kernel headers. That stuff
was added relatively recently:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ba0a6c9f6fceed11c6a99e8326f0477fe383e6b5

If I'm reading the dates correctly, this commit wasn't in 2.6.31.

As a side note, there is already a patch floating around to fix that commit,
which apparently broke stuff.
