Markus,

it is interesting, that you could not went trough with all of your stuff
at once, 94 patches or so, IIRC, and Manu was the one who tried to
explain to you, that this can't happen this way, since you affect other
drivers.

Short time later, Johannes and Oliver did open simple ways for you, you
came back with the same and asked Mauro to review it within 24 hours or
you would made up a major listing everywhere,  what lamers we are and
that this would immediately show, that you are the only one we need ...

It is still the same ...

By all respect, not that way.

Hermann
