If for whatever reason you can't use 2.4.x on it right now, in 2.2.19pre3aa4 there's an hack to do tcp_sendmsg checksum and all the copy_user (copies between pagecache and userspace) with the big kernel lock released (so that it can scale better in SMP). That's ugly but people on this list asked for this feature and since it was very fast to implement it I added it. But don't expect anything like 2.4.x SMP scalability!
