Did you tried http://www.linux-vs.org/~julian/route-noarp.txt ?
There is a section "Notes for the LVS users".
This "new" way is again from two parts:
- filtering remote probes
- selecting the right (unique) source address for our probes
With this way of handling the VIP can be on any device while
the hidden flag has another semantic and for some setups it is not
allowed to configure VIPs on ARP devices.
