I was able to get this to work w/o much hassle at all--modifying 
hobbitd/larrd/do_vmstat.c to include the rhel3 array and lib/misc.c, 
lib/misc.h to define rhel3 as an os type did the trick.  Then I created 
a vmstat graph config (vmstat_rhel3) in hobbitgraph.cfg that uses all 4 
cpu status parameters and referenced that in bb-hosts for my rhel3 
systems.  Like I said in my last message, the vmstat bottom feeders on 
the clients have to be configured to set the BBOSTYPE to rhel3 when 
sending the data to the hobbit server for this to take effect, so this 
is more of a positive test result than a general purpose solution.  I 
guess the point of this email is that it works just like I wanted it 
too.  Getting it more generalized is my next step.
