No ip_vs_ftp?

I've never done ftp behind a load balancer before, but it seems like
that would be required.  That module is available to me on my 2.6.11
kernel, I won't guess as to its availability on your kernel version.
You'll need to take a look.

[todd@tlyons /lib/modules/2.6.11-12mdksmp/kernel/net/ipv4/ipvs]$ ls 
`pwd`/ip_vs_ftp.ko.gz
/lib/modules/2.6.11-12mdksmp/kernel/net/ipv4/ipvs/ip_vs_ftp.ko.gz
