OpenLayers does not have native coordinate system transformation  
support (expect for spherical mercator) built in.  It uses an external  
library called proj4js which is a port of proj.4 algorithms to  
javascript.  AFAIK there is no work being done to create a javascript  
version of CSMap, which would be a precursor to being an option for  
use with OpenLayers.
