I hope this really helps the graphics on my late 2001, 600mhz iBook. I think it has a rage 128, right? Although, with only 8mb of VRAM, I can't expect too much...
One thing that I've been having problems with that I'm not sure if the update will fix, is that when I un-plug my iBook when it's asleep, and then I wake it up, the mouse is sometimes erratic, the volume/brightness keys don't work, and if I go to the mouse control pane, the whole computer freezes. Other times, the mouse and keyboard won't respond at all, but I know the computer is running fine, because the animations are still going, the time is still changing, and everything else is normal. It's really annoying, seeing as that I am constantly on the go with my iBook, and I don't like to restart it every time I have to go somewhere...
BTW, I can avoid the problem by un-plugging the iBook while it's awake, but that's just not as fun 😛
