I think most people (at least myself) have moved beyond a mactel with
linux, which may explain inactivity. I still think it's an outstanding
issue, but I have no way of testing it.

Title:
  Appletouch touchpad driver produces jumpy two-fingered scrolling

Status in Mactel Support:
  New
Status in “xserver-xorg-input-synaptics” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: xserver-xorg-input-synaptics

  My system is: Linux richard-laptop 2.6.28-11-generic #42-Ubuntu SMP
  Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux.  However, this issue
  applies to at least Intrepid and Jaunty, 32 and 64 bit, running on
  Apple Mac hardware that uses an Appletouch touchpad.  It has also been
  reported in the Gentoo and Debian forums.

  From what I can find on the Net, the Appletouch touchpad was first
  used in February 2005 for the G4 aluminium PowerBook, and last used
  for the Macbook Pro in its 3rd generation, then 4th generation Intel
  Macbook in early 2008.

  The issue is with two-fingered scrolling.  The Appletouch features the
  ability to detect two (or three) touches.  OS X uses this feature to
  enable scrolling, similar to a scrollwheel on a mouse.

  The synaptics driver causes the simulated scrollwheel to start moving
  as soon as one places a second finger on the touchpad.  That is to
  say, placing a second finger causes the trackpad driver to deliver
  scrolling signals, which means that attempts at vertical scrolling
  feels jumpy, or over sensitive.

  There was an update to the OS X driver that fixed this situation for
  Apple.  I guess that it detects the second finger and programmatically
  ignores the first few scrollticks, thereby 'deadening' the output.
  This is what we need.

  The synaptics driver allows for some modification, but not for
  multitouch input.  This needs to be fixed at source code level.
