[jQuery] $(document).unbind('ready');

[jQuery] $(document).unbind('ready');

Is it possible to unbind functions from the $().ready() event?
I have scripts that do this:
$(document).ready(function(){ /* make things happen */ });
$().ready(fnRef);
In a following script I'd like to unbind these and have tried the following, problem is it doesn't seem to work:
$().unbind('ready');
$(document).unbind('ready');
Any suggestions? A quick search of the docs and maillist didn't reveal a solution.
thanks in advance,
Jim
