Thanks for the idea. I gave it a try, but nothing new occurred.
I've further played with the RAM, and I think I really don't have a problem with the second slot. I think I got the beeps because I didn't have it pushed in all the way. Reset the RAM, and it works fine now in both slots, though I'm still not sure the old RAM card is any good.

See Mac OS X: "Broken folder" icon, prohibitory sign, or kernel panic when computer starts
Will it boot in Safe Mode? See
What is Safe Boot, Safe Mode? (Mac OS X)
Takes a while to run, but it usually "fixes" problems.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
Kernel panics are usually caused by a hardware problem – frequently RAM, a USB device or a Firewire device. What external devices do you have connected? When trying to troubleshoot problems, disconnect all external devices except your monitor, keyboard and mouse. Do you experience the same problems?
Do you have an Apple Hardware Test disc? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.
May be a solution on one of these links.

Thanks, Tom, for the response, but I've tried all the things suggested in those links. The first one you included is actually for older versions of OS X, but I went to the similar article for 10.4 or higher, and tried all of those steps.
And as I said in my original email, I can't get into Safe Mode, or start up in Single User Mode in order to use Disk Utility or fsck.
There are no peripherals attached. I ran the Hardware Test early in the process, and all items passed. I didn't run it in Loop Mode, however. But now I can't run the test, because I can't get it to read any disks.
As I explained earlier, Current Symptoms are that I can't get it to start up on its own, or with the install disks inserted; the farthest I can get is the start up tone and Apple logo, which then turns into the prohibitory sign.
