Trying to implement a thread queue for page with 6 update panels

I am attempting to write a FIFO thread queue for the dashboard portion of a portal application. There are 6 update panels that refresh independent of each other about every 60 seconds, so there are a lot of postback collisions and I need something to save postbacks and re-issue them when the callback from the prior async call is returned.

It looks like there has been quite a bit of effort put into this, but none of the code I could locate would work in my situation because of various "can't find id", "null reference", and "object does not have this function" -related js errors.

Here is what I have so far:
Sys.Application.add_load(ApplicationLoadHandler)

function ApplicationLoadHandler(sender, args)
{
var prm = Sys.WebForms.PageRequestManager.getInstance();
if (!prm.get_isInAsyncPostBack())
{
prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(CompleteRequest);
}
}
// initialize a queue
var myQueue = new Array();

function CompleteRequest(sender, args)
{
if(myQueue.length > 0)
{// fire correspond event again of the item cached
var control = $get(myQueue[0]);
setTimeout('__doPostBack(\'' + control.id + '\',\'\')', 0);
Array.removeAt(myQueue, 0);
}
}
function InitializeRequest(sender, args)
{
var prm = Sys.WebForms.PageRequestManager.getInstance();

if (prm.get_isInAsyncPostBack())
{
// if it's working on another request, cache the current item that cause the request
args.set_cancel(true);
Array.add(myQueue, args.get_postBackElement().id);
}
}

if(typeof(Sys) !== "undefined") Sys.Application.notifyScriptLoaded();

Even if this did work, it wouldn't do what I want it to do because '__doPostBack(\'' + control.id + '\',\'\' would strip out all of the eventargs that were sent along with my postback (for instance, if the user initiated the postback via mouse click) and turn "doPostBack('gridviewSomething', 'Select$1')" into "doPostBack('gridviewSomething')", which is clearly no good.

This code will properly interrupt postbacks and save them to queue, but upon callback and re-initiation I get problems. Anyone have any suggestions? I feel like this is so close and I am loosing my hair over it, so help is much appreciated.

Merry (early) Christmas.
