I've built a php object called ~jgreidy:cul_gsa_search() to handle the interaction with http://web.search.cornell.edu and parse the xml results it returns. I also have an example wrapper script and ~jgreidy:css file to display the search results. I'll be happy to share this wrapper scrip with anyone who is interested, but it is written for a site that uses the Smarty template engine.
Style the results
I've attached a ~jgreidy:css stylesheet for Cornell Google search results as a starting point. Certain results may be marked as 'Keymatch Results' and these get special styling.
