I'm starting this thread for anyone to post any problems they're having AFTER upgrading to 10.5.1.
For me, I have a self-waking MBP, sometimes wakes up after a few mins, sometimes after a few hours. (although this problem was reported before 10.5.1, but I didn't have it myself before, so I've stuck it in).
