Can you guys test passing in "psmouse_noext=1" instead?
The thing is, the psmouse initialization in 2.4.x does _nothing_. Nada.
Zilch. Zero. And it obviously works fine. So the 2.6.x code is apparently
The extended psmouse detection code will try different things, and one
thing in particular is that the Logitech magic ID matching sets the
resolution to zero, while the IntelliMouse thing sets the rate to 80.
I don't know what the proper thing to do is, but I'm pretty certain that
the current mouse initialization has got to go. It clearly breaks setups
that worked fine in 2.4.x, and the 2.6.x doesn't actually have any
_advantages_ that I can tell. Maybe Vojtech can inform us.
Passing in "psmouse_noext=1" gets you close to 2.4.x behaviour.
