Hi,

I am unable to reproduce your problem. On both
kernel-image-2.4.27-2-686 2.4.27-10 and
kernel-image-2.4.8-2-686 2.4.8-16 I am able to 
successfully  modprobe (not insmod!) ip_conntrack.

On 2.4.27-10 I see
   grep ipfrag_flush /proc/ksyms
   c01dfdf0 ipfrag_flush_R290ad055

And on kernel-image-2.4.8-2-686
   grep ipfrag_flush /proc/kallsyms
   c023ccb0 T ipfrag_flush
   c023ccb0 U ipfrag_flush	[ip_conntrack]

For reference, the md5 sum of the image files are

fcbebdc8a6ca001448bd7687f22c5111  /boot/vmlinuz-2.4.27-2-686
9cbb21574407fd163b9007afc87ef2f4  /boot/vmlinuz-2.6.8-2-686
