 I would not call this change a fix -- the cure is worse than the disease.

 We should maintain a table of references to ignore for modpost then.  It 
should be discarded together with other init data and given the number of 
such references it would be rather minuscule compared to code held in 
memory unnecessarily throughout the boot cycle of the system just to 
satisfy a debugging tool.  Which is a very useful one, no doubt, but 
please do not forget about the common sense.
