Here's a problem I've been having with Leopard on my 2.2Ghz MacBook Pro:

When waking from sleep by opening the lid, it sometimes takes a very long time for the screen to turn on. The keyboard lights up right away though. Sometimes the screen never wakes up and I have to force shutdown and restart.

And, sometimes when waking from sleep, I get a very jumpy cursor and have to restart to get it back to normal. I've heard this has something to do with Airport?

Anyhoo, those are a couple of things you might want to look for
