Now that I've run with the cpu frequency applet set to either 2000mhz or 
performance, I have noticed that gray outs are still common and 
frustrating as I try to use my system. On a whim, I changed the cpu 
governor to ondemand, and what do you know, the gray outs went away...

It seems I was a bit hasty when I made the declaration that "things are 
responding much more quickly now" above in the quote.
