Alex and I follow-up on this issue on IRC, but just for other's  
benefit that may have run into this.

Other than using metatiles like Jay recommended (which is great for  
tilecache), in OpenLayers you can also use the singletile mode.

It may not be ideal from a perfomance perspective but it is an easy  
workaround:
