Public bug reported:

Binary package hint: linux-image

Tested on Intrepid Daily Live i386 CD, 31AUG2008:

Starting up the CD on a Macbook Air or Macbook Pro Penryn, both of which
use the bcm5974 trackpad driver, the mouse pointer is initially frozen.
The reason is that the bcm5974 driver only mimics a synaptics touchpad,
not a mouse. After configuring the synaptics driver everything is fine,
but the default behavior is simply not going to work well for first time

The suggested remedy is to add a second, default, configuration to the
bcm5974 driver, where it works as a multi-button mouse, using multi-
finger options. This will give several benefits:

* The default Xorg configuration will pick up the mouse input interface,
resulting in a functional mouse pointer.

* Multi-scroll will work without the need to configure the synaptics

* Multi-finger button emulation, which currently only exists in the
mactel version of the synaptics driver, will work out-of-the-box.

Basically, unless multi-finger-tapping is wanted, no reconfiguration of
Xorg or bcm5974 will be necessary. A patch will be submitted shortly.
