Wey-yi,

Will this cause any issues with the existing 2.6.35.12 iwl-5000 driver? 
Is the version 5 API backwards compatible? Ubuntu installs 
iwlwifi-5000-5.ucode by default in order to support compat-wireless 
backports from 2.6.3[678], so I'd hate to break those folks that are 
using the stock 2.6.35.y driver.
