I'm not entirely sure that you can reserve a range of addresses as such.
One notes that under 2.4 once can in fact bind to the port 610000-65095
that are used for NAT[1]. It seems that the the only reservation that
is done is to set the ephemeral port range not to overlap with
these ports. That and telling users not to bind to these ports.
You can change the ephemeral port range under 2.4 by manipulating
/proc/sys/net/ipv4/ip_local_port_range
