2.2.17 kernel compilation problems

[sndtrn27@xxxxxxxxxxx]

hi all
      i have mandrake 7.2 installed (kernel ver: 2.2.17-21mdk). i had patched
the kernel for TCP connection migration  by a patch by snoeren@xxxxxxxxxxx from
the site http://nms.lcs.mit.edu/software/migrate.
the kernel compiles properply but when booted from this kernel the network does
not come up.
the error is that no                        modules.dep
file is generated.
if anybody has any solutions please help me out.
thankx
