i just finished opening the display, tried for what seems like eternity to remove those 2 screws with the smallest (and that one is small) screwdriver i found, no way.
then i decided to just open the case (ie. keyboard) as explained on fixit.com (did that several times to change the hd), then worked on the 4 screws holding the screen, first the left ones with the right ones fixed, then you can very easily lift the display some 5mm without actually removing any wires and easily work on the screw in the display, then reattach the display to the casebottom, open the right screws, repeat. very easy this way.
you voir your warranty anyway so you can just as well open the whole damn thing and admire the gadgets inside (btw, 320gig is around 55e, which is i guess 80$ hehe right now, might think of chaning that at the same time..)
good luck. if anyone needs pictures or advice, let me know...
