Dear Ross

We have a very grave problem with you guys. You do not develop an open
source driver in stealth mode, and not release code until some undefined
future. This is called forking. And forking means taking the extra hit
when main stream is advancing.

I've been changing this driver and supporting code, and even if not posting
every change on ML, so not to make noise, I pushed any new version to the
public tree every time. So anyone that monitors the tree can provision for
my changes and see where I'm going with this.

I've been monitoring your tree, and there was not a single change. If you
are making progress you should make them available, as soon as they advance
so we can see and adjust. (And/or maybe not make the same effort twice?)

I don't think so. Did you see the latest version of this driver. It is
so small. Any changes you will make, will probably be additions and
enhancements. I do not see how it will make such an extra work.

Show me the code, If I see that you are right I will make changes
accordingly, but for now I cannot see why it can make any kind of
problems.
