Public bug reported:

Binary package hint: xorg

Found using the Lucid alpha 1 liveCD

This is one of the weirdest bugs I've ever seen, but the macbook 2,1's
mouse cursor is being controlled by the accelerometer, such that the
best way to use the mouse is to tilt the laptop.  Whenever the laptop
moves slightly, the cursor will reset to a specific X,Y on the screen.
However, the X,Y it resets to is being determined by the accelerometer.

I've tried modprobe -r appletouch (the touchpad driver in macbooks), and
it segfaults and crashes X.  modprobe appletouch does the same.  It
seems to not be related to the appletouch driver though, since the
problem persisted after modprobe -r (which did work, despite the seg
fault - after restarting X, I could no longer control the cursor with
the touchpad at all).

I've attached dmesg, syslog, and Xorg.0.log - sorry for not using
ubuntu-bug to report, but Xorg.0.log kept flushing after restarting x,
so it wouldn't contain traces from the segfault.  Let me know if you
need anything else.

This bug, while somewhat humorous, still makes Lucid useless in the
meantime and I won't be able to install until it's fixed.
