Now I have rebooted the old laptop under 2.2.17. It was pretty ugly. I suspect (because this is what I've seen with incarnations of this problem in previous versions) that the video hardware was still upset with whatever happened with 2.4.0-test7. A full shutdown/power off and reboot cleared the problem.
Note that this problem has only appeared after rebooting from a 2.3.x or 2.4.0-testx kernel without a full power down. As long as I never bring up a newer kernel AND do a shutdown -r, I don't have this problem.
I'm a little puzzled that my previous response hasn't appeared on this list yet but I've seen long delays before so I guess I shouldn't be too alarmed. Basically, it came down to noting that it's difficult to move a video card from a laptop and that the problem seemed to have gone away after I rebooted to 2.2.16 (though I recall now seeing some corruption while it was booting, but nothing like the full-scale lockout I had with 2.4.0-test7) -- the keyboard was usable under 2.2.16.
