That's more insight than I managed. However, I'm afraid I'll leave that as
an academic question.

Initially I suggested a kernel-headers-2.4 rpm, because that turned up in
the first 'rpm -qf /usr/include/linux' that I tried. So I did 'rpm -e
kernel-headers-2.4<whatever>' with a force, but the file remained (not
surprisingly). 

I finally gave up and yanked all the other files off to a temporary
location on another partition, then did a reformat (mke2fs) of the /usr
partition. Now I've moved everything back to the reformatted /usr, and
everything seems more or less sane. 

Now I must build /usr/include/linux, which I've done by making a symlink
to /usr/src/linux/include/linux/, per Yaron's suggestion, and to match
another RH7 box here.
