You might try looking at "Cache Memory Performance in a Unix 
Environment" by Cedel Alexander, William Keshlear, Furrokh Cooper
and Faye Briggs, Computer Architecture News, Volume 14, Number 3,
June 1986, pp. 41-70.  They have lots of numbers and graphs and
the traces they use to drive the cache models are obtained from
a system running Genix and include the kernel, unlike most such
studies.  The traces are obtained by modifying the hardware of
a National 32016 based box.
