I think you could insert in your document a <div> with an
id="errorMessage" (or whatever)
and then change the callback function of $.post so that it puts the
response message in the div.
for example
$.post('check.php',
{
username: $('#username').val(),
password: $('#password').val()
},
function(data){
$('#errorMessage').html(data);
// but you still need some check to see if the form is ok
// what does 'check.php' send back in case the form is
ok?
// I assume nothing, so:
if (data != "") return false;
else return true;
});
now I'm just thinking that maybe doing as I suggested wil not work,
because $.post is an asynchronous request.
you may want to lock the page somehow, and get a synchronous request,
and have the form submit waiting for the response...
not sure (I'm not that expert I fear), so have a look here

actually I don't know how that would work.
but you can try and let us know :)
good luck
