Attached is a small patch that will add support for
  ethtool -i
to the prism54 driver.

ethtool -i queries the specified ethernet device for associated driver 
information.

This helps tools like Fedora's system-config-network to provide GUI 
management of network devices.
I learned how to write this patch by reading the ipw2100 driver code.

Thanks for considering to take it.
