I wish I could, let me ask you...I have a perhaps similar issue. I had to reflash the kernel and file system after installing pr 1.3 due to my stupidity. anyway so I have a blank slate. I installed advanced-power which worked perfectly on pr 1.2 and my battery bar swoosh gone. I uninstall advanced-power and I get it back. here is a link to the thread, nobody has an answer as of yet.
