I have a MacBook (white) 2008. Recently I upgraded from Leopard to Snow Leopard. The upgrade went fine, then I tried to open Safari and my onboard keyboard and trackpad froze! I'v done a restart, I've reset the PRAM and nothing responds. I attached a USB keyboard and use my Bluetooth Mouse with NO problems and am able to use the MacBook, though the onboard stuff still unresponsive. I am curious if there is a firmware update that I am missing and if anyone else has run into this problem?
