I think we are talking about the same thing.  From a section of my
.bashrc that hasn't been touched for quite a long time:

        alias make='nice -20 make'

The niceness polarity is such that the make is disadvantaged.

The machine is a crappy uniprocessor.  I just wanted to run a
well-tested ACPI configuration and GENERIC.MPACPI was the only one I
saw.  It wasn't clear what bits I could turn off to create a fully
functional uniprocessor ACPI kernel.

Just to explain why I'm bothering with ACPI; I'm setting up a system
that will eventually be used by a very non-technical person.  I'd
really like to intercept the front-pannel power and reset buttons so I
can do a clean shutdown and have one less thing to worry about.
