Hm.  That would be a regression introduced by commit
a491486a2087ac3dfc00efb4f838c8d684afaf54 I think.

Your patch seems like the correct fix.  Could you make it a strip
level of 1 and add the appropriate Signed-off-by line?  If so, we
should probably push this to -stable for 2.6.22 and be sure to get it
into 2.6.23.
