What does "does not work" mean?  From the patch, it appears that the
machine paniced?

This is important because without a recognisable description of the
failure it is hard for people to determine whether your patch might fix
a problem which they are observing.

The patch applies to 2.6.36, 37 and 38 (at least).  Do you think it
should be backported?  If so, how far back in time is it applicable?
