Bug description:
  SRU justification
  ============

  [Impact]
  Many modern notebooks need i2c-i801 kernel module to function, but it is 
blacklisted by /etc/modprobe/blacklist.conf, which gives a very poor user 
experience.

  [Test case]
  1. Install Ubuntu
  2. Check touchpad works or not
  3. Install the fixed kmod package
  4. Confirm touchpad works

  [Regression Potential]
  i2c-i801 was blacklisted due to bug 16602. The user complains an HP Compaq 
nc6000 notebook cannot suspend without blacklisting i2c-i801. While this is a 
way to workaround the suspend issue, the proper fix should be in linux kernel. 
Since nc6000 was a machine sold in 2004, it is too difficult to find someone to 
verify if it will regress due to this SRU. The rationale to blacklist it is: 
https://bugs.launchpad.net/ubuntu/+source/hotplug/+bug/16602/comments/5, 
however it is no longer valid nowadays on modern computers.

  Besides, there look like to be a quirk in linux kernel that fixes it:

-----------------------------------------------------------------------------------------------
  Original bug report:

  We have a Lenovo Thinkpad machine that requires i2c-i801 kernel module
  to work, but it is listed in /etc/modprobe/blacklist.conf in Ubuntu.
  To use the touchpad, users have to remove the i2c-i801 line manually.

  i2c-i801 in blacklist.conf is a very old workaround to fix HP compaq nc6000
  (Bug #16602), this module should be removed from blacklist.

  There is also another bug (Bug #1475945) that needs this module for
  Acer trackpad to work.
