Thanks for taking the time to reply time, Dennis. I ran cpuburn as you suggested. Specifically, I ran the burnK6 binary for about an hour (from an xterm, and I also had other stuff like galeon running simultaneously) and didn't get any hiccups. Monitoring with top, I saw that I had 0% free cpu during the test.
However I also later ran the burnMMX binary, and that one would quit after running a few minutes without printing any error messages to the screen - nor did it leave any messages in /var/log/*. Dunno if that's normal? Shouldn't it keep running until I kill it?
Can I draw any conclusions thus far? Could I conclude now that the CPU and RAM are OK (because of the memtest86 and cpuburn tests)? Also, assuming that all of my hardware is OK (yes a big assumption), could the problems I have be due to a misconfiguration or otherwise software problem?
As for swapping parts, I don't have any extra computer parts. Given the nature of these kernel bug messages in the syslog, can I use that fact to logically limit the range of hardware that can cause these problems? I.E. can I say for example that malfunctioning PSU, RAM, CPU or Mobo can cause these symptoms, but that the ISA sound card, or the video card would not? Or do I have no choice but to suspect each and every piece of hardware in my box?
I would like to narrow things down if possible, but don't have the experience/knowledge to make these judgements myself. Which is why I seeking advice, of course.

As I mentioned to John, I'm still a newbie and don't feel comfortable yet in my competency to replace the kernel. I have a lot of (newbie) time invested in this installation and don't want to break it by messing with stuff that's way beyond my understanding.

I'm not clear whether you intended these suggestions to apply after I've changed the kernel, or also to my current setup.
Assuming you mean applying it currently - grepping for klogd in /etc shows that mandrake uses an environment variable KLOGD_OPTIONS to run klogd. This was set to "-2". However the variable is set to this value in no less than 32 different files. 24 of them see to be related to runlevels (4x6), and 8 unrelated. This means that (if my logic is correct) that the same variable is set 9 times for a particular runlevel (rl-3 in my case). Which one should I change that won't get overridden? Or should I change them all, or use another approach?
(Thanks again for your help - wyleus signing off)
