modules.ofmap not in a package?

[hendrik@topoi.pooq.com]

I'm running tiger.

Aside fron vast numbers of messages about files in /usrX11R6/bin 
(which I imagine will go away when the xorg transition is complete)
there is one other:

> --WARN-- [lin001w] File `/lib/modules/2.6.12-1-amd64-generic/modules.ofmap' does not belong to any package. 

Is this correct?  Is modules.ofmap really supposed to be there?
And if so, 
  why isn't is part of a package?
And if not, 
  why does the corresponding one for 2.6.15 evince no complaints?
