No problems on my 10.4.9 update
I am also on build 3188 and have had no problems on any builds. Only issue is when I unplug my USB mouse and plug it back in I lose it's movement, but not the clicking. Track pad still functions though. I usually have to shutdown the VM to fix the USB mouse issue.
I followed almost all the MacFixit steps when I upgraded to 10.4.9 from 4.8, including cloning my HD to a FW drive and booted from it. But I did use Software update then downloaded the combo for future needs, should they arise.
