Have you considered putting a proxy / load balancer in front of it (running on a modern OS :) ) - varnish, for instance, or something like nginx - that can absorb the workload of managing the TCP connections and just hand off the individual requests to the old Apache box on the back-end? There are others, too... haproxy... perlbal... I'm not sure how effectively they work at TCP offload, but something like varnish or nginx should do the job. It wouldn't require any changes to the actual server on the back-end, except *maybe* changing an ip address or port, and could be done pretty much entirely through DNS changes/ tricks.
(I say this with no real knowledge of your infrastructure, but in theory, it should work.)
