My bad. 

It was not the "lease" stanza what you had to edit. I overlooked the 
"dhclient.conf" file but "man dhclient.conf" confirmed the lease is used 
when the client cannot connect to an existing DHCP server, which is not 
your case :-)

And from man page I can't see an option which you can configure from the 
client side to define a renewal interval... hum.

I usually have several devices that can act as DHCP servers but well, if 
you only have a router available you can install a DHCP server (or run a 
LiveCD with DHCP server configured) in a separate computer... unless you 
only have one computer in such case no DHCP server is needed at all :-P
