Why not? Granted, the data will be averaged out and you won't be able to go 
more than 2 year back (unless you use Stef's script), but the "Metrics Report" 
can do this.

E.g., by choosing the relevant details, I get a URL like this:
http://hobbit/hobbit-cgi/hobbit-hostgraphs.sh?start-mon=2&start-day=25&start-
yr=2009&end-mon=2&end-day=26&end-
yr=2009&hostname=$HOST&testname=la1&DoReport=Generate+Report

, and you can also do it by zooming in to the graph on the cpu page that 
covers that time frame.

wget 'http://hobbit/hobbit-
cgi/hobbitgraph.sh?host=$HOST&service=la&graph_width=576&graph_height=120&nostale&color=green&graph=hourly' 
-O $HOST-`date +%Y%m%d`.png

You could of course 'use RRDs;' instead, to access the RRD data directly, 
instead of post-processing data that has been interpreted to an image.
