IP tunnelling with new Red Hat Patch?

[Nigel Hamilton <nigel@xxxxxxxxxxx>]

Hi,

	I'm setting up my second LVS cluster and went to the UltraMonkey site 
to download the latest sources.
        I installed the new ARP rpms for Red Hat Enterprise 3.

	I want to set up an IP tunnelling cluster(IPIP). On the first cluster I 
normally patched the kernel and changed /etc/sysctl.conf with:
        net.ipv4.ip_forward = 1
        net.ipv4.conf.all.hidden = 1
        net.ipv4.conf.tunl0.hidden = 1

        But this time I get this error:

        error: 'net.ipv4.conf.all.hidden' is an unknown key
        error: 'net.ipv4.conf.tunl0.hidden' is an unknown key

        Do I still need to patch the kernel?
