Ok... Thanks!

Oh.. I know. I have experience with bad datasheets too... :)

Where is the latest version? I have a patch to linux-2.6.12-rc3. I
don't know if it is the latest version.
Are you hacking this driver now? I'm asking that because if the answer
is yes, we can change the same thing at the same time, and maybe it
will not be a good thing.

I'll do that.

Ok. I will start today!
