David,

It shouldn't be hard to re-enable the GIO driver in your local build
but there are "issues" with the way it tries to adjust the georeferencing
post-creation.  Likely the best way of dealing with this would be to rewrite
the export support as a CreateCopy method which would ensure I know
the georeferencing at the point the grid coverage is created. 

To re-enable the GIO driver, I think you can just call uncomment the
call to GDALRegister_AIGrid2() in gdal/frmts/gdalallregister.cpp.  But to 
fixup the code to set the georeferencing will require a bunch of development.
If you need it, perhaps you could write me a little more detail about what you
need to accomplish privately.  

I have dug into the format before with the idea of adding create support
without use of the ESRI DLL but failed to master the format well enough
to create valid datasets.

Best regards,
