When I got home, the old problem showed up. I decided to disconnect all the cables and put them in one by one after zapping PRAM and PMU. Everything worked until I plugged in my Brother MFC-8640D into a PCI USB port. The disappearing cursor problem showed up again. When I switched it to a built-in USB port, I had no problems.
What make and model USB PCI card is that?

This response is truly prescient but too late for me.
Today I went to the Genius Bar at an Apple store in Manhattan Beach. The tech started my computer while zapping the PRAM. He also reset the Power Management Unit (PMU). Everything worked just fine at the store. The cursor did not disappear. The computer went to sleep and I could wake it up just as it was supposed to work.

What I think I had done was to move the MFC connection to a PSI port. My motivation was that I would use the PCI ports for connections to devices that did not have to be active during boot or log-in time. The keyboard and mouse have to be active during this time. The MFC does not have to be active then, so I thought it would be safe to make the change. I was wrong.

I you really would find that information useful, I will look at the card. For now, I will just list what the system profiler found.

Well I think if anyone might find it useful, it would be *you*, since you are the one having problems with it, right? ; ) It seems you've found an incompatibility with this PCI card and Mac OS X's sleep functionality - maybe the card's drivers don't support deep sleep. Depending on how old the card is, the make, and model, you may be able to look it up online and find a work-around solution to the problem.

At this point, I do have a work-around. Next time I open my Mac, I will check out the card and report the results to the manufacturer and to Brother.
For now, the answer is to use one of the built in ports rather than the PCI card.
