So it looks like this is fixed by v3.3-rc1~105^2^2~13^2~4 (tpm_tis:

Jurij, what kernel were you testing against?
It would be nice to pass this to Greg for inclusion in 3.2.y and
perhaps 3.0.y kernels. Do you know if 3.0.y is affected? (If this
patch is tested against something close to upstream 3.0.y or 3.2.y,
I'll be happy to submit it to stable@).
