Felix, thanks again. As for KDE, this link's info is dated 2012, and so
I assume it's referring to KDE4, whereas I'm running KDE3.5. I can hope
that my KDE3 will continue working in the long run, but if I have to
ditch it, it'll be ok, and probably even a good thing :=)

I tried startx'ing with only bare IceWM rather than KDE3, and got no
different behavior.

Wow, there's so much here that I am in no position to understand. Your
hardware situation seems very similar to mine, but there are differences
too (below).

There appears to be nothing related to graphics in my BIOS menus.

Not apparently true for my machine (Dell XPS tower). To begin with, Win7
can use both displays in this setup just fine :=)

My #2 is not always blank, but occasionally weird things appear. And
yes, both of my GPUs are reported by lspci in a way that looks
completely normal. lspci -k shows which drivers are being used.
Nothing seems out of ordinary.

Nice to know... I would be perfectly happy to do this if I had the
right kind of monitors or cables/converters to do so, which I don't
right now :=)

I think I'll play with static configs a little longer, and then just buy
an HDMI-VGA converter, so I can have both monitors driven off the
Intel card, and be done with it.
