Is there a howto for this sort of thing?  From what I read here and
other places, some laptops are really confusing but there are even
desktops that have issues with some new features.  How does one get a
idea of what they should try?  I remember a list ages ago when I first
installed Gentoo that has a list of CPUs andsome of the options a person
could put in make.conf.  I think we need one of those, maybe on a wiki
or something, that lists models and what setting really work.  I think
laptops would really benefit from this.  I have never had a laptop but
they seem to be tricky to be nice about it.
