I did this because many people were using the standard
distribution libraries, which don't work with copyback
enabled.

For a real treat, download the linuxplanet-2.2.13 kernel
sources from MontaVista.  It includes some configuration
options that will be in the 2.3.xx sources once I get
them to compile :-).  For example, the copyback cache
and 860 Rev. B cpu6 silicon errata are configurable.
