Okay, as long as you've rebooted then, the running kernel should match the modules. Here are a couple more thoughts:

1. Have you tried running insmod or modprobe on the ipvs modules manually. Maybe you would get helpful info with a -v flag or two. Do the modules load properly?

Yes, I have loaded both ip_vs and ip_vs_wlc manually. In both cases, I have tried the -v flag and it returns nothing alarming:

# insmod -v ip_vs.o
Using ip_vs.o
Symbol version prefix ''
# insmod -v ip_vs_wlc.o
Using ip_vs_wlc.o
Symbol version prefix ''

2. I wonder if ipvsadm needs to match ipvs. Have you tried compiling that with your current kernel source tree?

Yes, I have tried compiling ipvsadm from ipvs-1.0.10 and from ipvsadm-1.21. In both cases using /usr/src/linux pointing to the right kernel source. In both cases I get the same error.

Good point. However, I always run the following commands when building or rebuilding a kernel:

# make menuconfig
# make dep
# make bzImage
# make modules
# make modules_install
# cp System.map /boot/System.map-2.4.21
# cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.21

Did you rebuild the entire kernel group (kernel + modules) after patching ipvs, changing the config settings, and compiling? Kernel module versioning is usually turned on by default, and that can cause problems when trying to load modules that weren't built at the same time as the running kernel.
