That is a good question, if whatever is providing his DHCP doesn't do
fixed assignments than he won't be able to do that. :-)

On linux, using bind DHCP server, you do something like:

        host wrt54g-bearsden {
                hardware ethernet 00:aa:bb:cc:dd:ee;
                fixed-address 192.168.0.10;
        }

to specify a fixed IP address for a mac address.

On my WRT54G wireless router/access point, there is a configuration web
page to specify IP addresses for specific mac addresses.
