Attached patch adds .gnu_debuglink section to the kernel modules pointing to the corresponding kernel modules containing the DWARF information. Please review the patch and apply. I've generated it against the debian/ kernel trunk from the svn repository. I would like to see this be part of the Squeeze release. So please apply this to the Squeeze kernel too.
