Matt,

Option (3) might be port the gio driver to current GDAL, possibly as a
runtime loaded driver.  I can't think of any reason it would be a problem
to get the old driver working with current GDAL - assuming you are
comfortable building GDAL yourself and doing just a bit of build-hacking
yourself.
