Basically I believe it would be just a matter of dropping the file in the data 
subdirectory. I can see some logic in ogr/ogrspatialreference.cpp to deal with 
IAU: prefixes, but you would have to test.

Something that should be checked is whether we have the rights to distribute 
that file along with GDAL.
