e100 weight reduction program

Corporate-authored device drivers are bloated/buggy with dead code, HW and OS abstraction layers, non-standard user controls, and support for complicated HW features that provide little or no value. e100 in 2.6.4 has been rewritten to address these issues and in the process went from 9247 to 2316 lines of code, with no loss of functionality. I'll talk about lessons learned and give guidelines to other corporate driver authors.
