@ tbreustedt: did you also remove the driver first (rmmod hid_multitouch)?
Also, you could try the same with i2c-hid:
sudo rmmod i2c-hid
sudo modprobe i2c-hid

Instead of odie's script you can also try the following for a "permanent" solution:
sudo touch /etc/pm/config.d/00sleep_module
sudo chmod 755 /etc/pm/config.d/00sleep_module

edit the file and insert
SUSPEND_MODULES="$SUSPEND_MODULES i2c-hid"

Title:
  Touchpad not working after suspend/resume

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 14.10 on an Acer Laptop, model: Aspire E5-571G-941Y
  $ uname -a
  Linux Acer-Aspire-E5-571G 3.16.0-24-generic #32-Ubuntu SMP Tue Oct 28 13:07:32 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

  Every time I suspend, the trackpad no longer works when resuming.

  I see several other people have the same issue with the same laptop here:
  http://ubuntuforums.org/showthread.php?t=2250002
  (some people say it's a 14.10 specific problem)

  I realize this report is very poor but please don't hesitate to request data / clarifications from me, I'll be happy to help.
