SubjectRe: binary kernel drivers re. hpt370 and redhat
I believe that companies will eventually see it costs less and the benefits 
higher to open source their drivers. But that is a conclusion and paradigm
that they will have to evolve to themselves, and shoving it down their
throats will only lengthen the process. The first step is to support their
hardware under the platform (linux), and that is what I am focusing on.

Thanks for the technical analysis and suggestions.
