I need to give you my kernel linker locking patch to avoid future pain.  It
fixes the kernel linker lock to actually protect all of the linker and adds
a foreach-style function to call a handler on each linker_file_t.  I haven't
committed it yet as it needs testing with ndis.  Maybe I will post it to
current@ tomorrow.
