Thanks, Dave - Other than the wc for the rrdtool dump and the actual size
of the files mine looks similar to yours. Here are the outputs for those
commands on my box:
$ ls -lh la.rrd vmstat.rrd
-rw-r--r--. 1 xymon xymon 213K Jan 30 14:53 la.rrd
-rw-r--r--. 1 xymon xymon 3.5M Jan 30 15:16 vmstat.rrd

The rrddefinitions.cfg file looks like this:
# Xymon RRD parameters
#
# This defines the number of datapoints stored for each RRD, and the
# RRD "consolidation functions" applied. See the rrdtool documentation
# for details.
#
# NB: Changes here only apply to newly created RRD files. To change
# your existing RRD databases, use the rrdtool utilities to modify
# your existing files.
# include additional sections
directory /etc/xymon/rrddefinitions.d
# Each section key is the column- or data-name reported from your
# client test. Typically this is "cpu", "memory", "tcp", or some
# custom test you have created.
# Definition for frequent ifmib polling (once per 60 seconds)
# The setup for this is identical in granularity to the default
# setup, but since data is fed into the RRD once every 60 seconds,
# we use 5 times as many Primary data points for each of the
# Consolidated data points actually stored in the RRD file.

Does anyone know when the line 'RRA:HWPREDICT:8064:0.1:0.0035:2016' was
added to this configuration by default?

That seems pretty bug to me. Mine are all under a meg.
When you run 'rrdtool info somebigfile.rrd' does it have a lot of different
data-sources ("ds")? Mine tend to directly correlate.
Here's some output from looking at a couple average rrd files for me.
