I had this experience some time ago. I was going to say it didn't 
seem to be related to OS X, but on reflection, I suspect the OS X 
installer loaded a newer version of firmware on my Mac (a 400-MHz 
G4), and I think the problem appeared at roughly the time I installed 
OS X, though it was many months before I started using OS X 
regularely.

In my case, the solution (not at all intuitively obvious) was to 
disconnect my Wacom tablet. If I remember correctly, other folks had 
similar problems related to other USB devices. I would suggest 
disconnecting all USB devices except your mouse and keyboard. If that 
makes a difference, I would look for any driver updates for your USB 
devices. I would also wonder whether there are any  additional 
firmware updates for your computer.
