Simply paste the following into
app/code/core/Mage/Adminhtml/Block/Template.php
public
function

{
Varien_Profiler::start(

extract (
$this

$do
=

if
(!
$do

ob_start();
}

try

Just be sure to remove the code again then you are finished. If there is enough demand for it I might package the change up into a new MageBase extension.
