You have lots of options:

1) Flash your wrt54G with DD-wrt or OpenWRT. Then you get dnsmasq 
running on the 45G.

2) Move DHCP to dnsmasq running on the Debian box and use longish lease 
times. If the DHCP server is unavailable for short while, the clients 
will just keep going and renew when the server comes back. The server 
can be down for half the lease time without any problems at all.

3) configure dnsmasq to use the linksys box as upstream server, maybe 
only for a local domain. This will only work if the Linksys stock 
firmware does DHCP-DNS integration in a similar way to dnsmasq. I don't 
know if that's true. (At least some of the stock firmware releases use 
dnsmasq for DNS, I think they use udhcpd for DHCP.)


Cheers,

Simon.
