yes, with document.getElementById you get the reference to a DOM-object. 
To get the OpenLayers-Map-object, you could declare map as a global 
variable:

<script>
var map;
// initialize OpenLayers-Map
function init() {
     // notice the missing var
     map = new OpenLayers.Map(...)
}
</script>

If you already can access mapPanel, a reference to the 
OpenLayers-Map-object is stored as mapPanel.map.

To check if your variables are global, simply type the variable name in 
Firebugs console window. If you get a clickable object back, you should 
be fine.

Hope this helps,
Marc
