Frank,
We are using subdatasets exposed by the Radarsat-2 driver (beta0, gamma, sigma0). gdalinfo complains when computing statistics for specific subdatasets:
Warning 1: Unable to save auxilary information in RADARSAT_2_CALIB:BETA0:c:\data\test\product.xml.aux.xml.
Computing for the whole dataset does save one set of statistics and histogram, but not for each subdataset.

Frank,
Building overviews has similar problem - overview for subdataset is saved as product.xml.ovr instead of independent overviews for each subdataset.

Robin,
I tried:
on a radarsat 2 dataset. The .aux.xml file held statistics and histograms after this, and a new gdalinfo confirmed (by not going through any slow computation) that the .aux.xml file was being used. I tested this on "trunk" and the "1.8-esri" branch. Can you provide more detail on why you think the values aren't being persisted?
