[CentOS] Using CentOS 3 in and LVS?

Is it possible?

For LVS you have to deal with something called the ARP problem (viz.,
the realservers should not respond to ARP requests for the hardware
address associated with the virtual IP).  This is solved with some
sysctl stuff for kernel 2.2.x and for 2.4.26+, but of course CentOS 3
is 2.4.21.

There's a kernel module "noarp" that's suppoed to work for all 2.4.x
kernels but I can't get its configure to work properly.  Does anyone
have any experience with this module?  Is there an RPM somewhere?
