redhat 7.3 module compilation

[mixo]

I got  'ipvs-1.0.3' from
  http://www.linuxvirtualserver.org/software/kernel-2.4/ipvs-1.0.3.tar.gz
I also installed 'kernel-source-2.4.18-3' and patched with

  cat /root/piranha/ipvs-1.0.3/linux_kernel_ksyms_c.diff | patch -p1

I skipped the other patch as I somehow it fails
 (cat /root/piranha/ipvs-1.0.3/linux_net_netsyms_c.diff | patch -p1)

I then procceed to compile the 'ipvs' modules and installed with
  insmod ip_vs_wlc.o
which succeded.

What I want to know:
 1. Why does the one patch fail?
 2. Why does 'make' on the kernel fail,but 'make deps' succeeds?
And
 3.  Without the patch, installing the module(even thout is compiled) give s
      
------------------------------------------------------------------------------------------------
      ip_vs_wlc.o: unresolved symbol register_ip_vs_scheduler_R4b2ae615
     ip_vs_wlc.o: unresolved symbol unregister_ip_vs_scheduler_R7abc3c96
    
 -------------------------------------------------------------------------------------------------
     Why?
 


P.S.

What I get if try to compile the kernel after applying the patch
