I have a cisco router with IOS v12.4

I have a pool of outside addresses which are statically nat'd to
internal addresses, such as:

ip nat inside source static 10.0.10.188 200.200.200.188
ip nat inside source static 10.0.10.189 200.200.200.189
ip nat inside source static 10.0.10.190 200.200.200.190

I also have a few static entries for DNS to statically nat to another
internal address such as:
ip nat inside source static udp 10.0.1.20 53 200.200.200.188 53 extendable
ip nat inside source static udp 10.0.1.20 53 200.200.200.189 53 extendable
ip nat inside source static udp 10.0.1.20 53 200.200.200.190 53 extendable

Presently I only have a few of the external DNS entries nat'd
internally to the one machine however I would like to have all
external port 53's on the 200.200.200.x network nat'd internally to
10.0.1.20.

I'd like to do this without having to have 255 additional static nat
entries for each of the port 53's.

I believe that using a route-map and pools is the way to do it however
I have not been able to come up with a working configuration.

I need you to come up with a working configuration which will allow me
to statically nat all UDP/53 ports on the external side to the single
internal address w/o having 255 ip inside source static entries.

You can go to Cisco.com and search for the Cisco COnfig maker. I think
It can handel what you are asking. Basicly you need to have a wild
card mask on the IP's
