I found after hours of searching a post on Steve's DigiCam forums that gave a hint for remapping hot pixels.
The hint was to go to sensor-cleaning mode and leave the mirror up for 30 seconds.
I did this (camera face down to keep dust out, since I don't have a good body cap at present), and tried 20 seconds of mirror-up.
Then I took a shot with the lens cap on the replaced lens, so it would be a completely black shot.
Looking at it in my editing program, and even maxxing the contrast, I saw only one hot pixel where there had been four or five before.
I then repeated the process, waiting 45 seconds with mirror up. After that, I see no hot pixels at all.
Time will tell if this is valid, or just a coincidence, but it's easy, it can't hurt anything if you keep dust out and have pretty fresh batteries, and it seems to have worked for me.
I wish I had called this "Found POSSIBLE Way" etc. but apparently I can't edit the title of my post. So don't consider this gospel by any means, but it seems a safe and promising way to improve things. It had been a LONG time since I cleaned the sensor, and before that I was cleaning it about every week to two weeks, and had very few if any hot pixels. That is suggestive, too.

An extraordinary collection of urban images. Congratulations to all participants, winners or not. It was very difficult to make a choice, and actually painful to have to choose in some cases.
This body of work deserves wider exposure, for sure.

Neither long nor boring. I like to hear details of how people use their cameras, and photography, in their work or for art/leisure. Thanks.

Hi. I was born in 1940 and have done photography, on and off, for about fifty years now. The price of wet-darkroom supplies led me to stop doing darkroom work several years ago, and I couldn't get enthusiastic about using commercial labs as an amateur unable to afford customizing. So digital photography has been a wonderful thing for me.
I use Panasonic, Fuji, and Pentax cameras; at the moment my only Pentax camera is the K100D; I have the kit lens, and the Pentax 40-mm "limited" pancake lens, a Focal 135-mm film-camera lens, a Tokina 28-mm film-camera lens, and a Tokina 70-200-mm film-camera lens in addition. To my mind one of the best features of Pentax is the ability to use any K-mount lens ever made. I think this is also very generous of Pentax -- the other mfrs. require you to buy new lenses in many cases. I like the solid construction of the camera but am not at all happy with its bulk, though I realize that, incredibly, it's one of the smaller DSLR's. Someday these cameras are going to be something to laugh at. (I don't understand why DSLR's have to be half-again as bulky as the best film SLR's.)
My photography tends to be "abstract" (for want of a better word) or images where pattern, texture, or even just the photographic tonal quality is the predominant interest. I am at Flickr: Photos from JRR KC and also on my own webspace at mindful dragon -- photos etc..
As long as Pentax remains in business, I do not think I would consider buying another expensive camera not made by Pentax. They have been innovators, maintain a low profile, are generous to users (see above), and have made, and do make, some really fine cameras and some of the best lenses in the world. It's hard to better those attributes.

Thanks for all the information in this thread. I searched quite a bit before finding this answer to my question ("Why am I stuck on ISO 200 all the time?"). I agree that this should be fixed, but probably won't. At least I got my best laugh of the day from the proposal that it won't be fixed because then the manual would be wrong. The same thought had entered my head about one second before reading that!
