Thanks for the suggestion.  Unfortunately, it didn't help.  That's assuming 
I've get lilo.conf configured correctly.  For example, the relevant line for 
Red Hat 9 is:

	append="root=LABEL=/ acpi=off apm=off"

I was using this system for several hours, and then left it alone for about 
an hour, and when I returned, it was in screensaver mode and hung again.  And 
in answer to Jeff's suggestion - I've switched off every BIOS setting I can 
find that looks remotely related to APM.  There's nothing that says I can 
explicitly turn power management off, though.

I'm not sure I'm on the right track with this, but the end of 
/var/log/messages from RH9 does seem to make  power management look guilty:

Thanks for the help so far.  As soon as I figure out something that works 
I'll definitely share it with the group.
