Only console.log()? Or console.warn() and console.info() too?

I can do it with regular expression search and replace.

EDIT

One thing I'm not sure what to do with though:

vBulletin_Framework.prototype.console=function(){
	if(window.console||console.firebug){
		var args=new Array();
		for(var i=0;i<arguments.length;i++){
			args[args.length]=arguments[i]
		}
		try{
			eval("console.log('"+args.join("','")+"');")
		}
		catch(e){
		}
	}
};
