[tproxy] tproxy in Ubuntu

Hey Guys, I'm looking at setting up Squid 3.1 with tproxy on ubuntu 9.10 server edition and was wanting to know from the list if anyone has had any luck with this? I'm aware I might have to do a kernel/iptables recompile, Is there a recommended version's to do this with? Are the patchs still needed? Regards Tristram
