Unresolved symbol hotplug_path in usbcore.o as a module (2.4.12)

I am not subscribed to the list please cc me on any reply

I have built the the 2.4.12 kernel with CONFIG_HOTPLUG set and the usb stuff 
all compiled as modules.

depmod -e  shows that usbcore.o has an unresolved symbol (which of course 
fails when the module tries to load) of hot_plug path. 

Looking through the code I can see that this gets defined in kmod.c - and 
there is an entry in System.map (I don't know each line means but 
hotplug_path is there).  I can also see the kmod.h (included by usb.c which 
eventually gets built into usbcore) defines it as an external reference.

What I have been unable to figure out is why depmod doesn't link usbcore.o to 
it.

I need the output from
  nm -A `/sbin/modprobe -l`  | grep hotplug_path
  grep hotplug_path /proc/ksyms System.map
