The configuration/script files to a proper hibernation/suspend for laptops like Asus U30Jc

# File: "/etc/pm/sleep.d/20_custom-ehci_hcd".
#
#This script is for some laptops like Asus U30Jc, and make the laptop 
#hibernate and suspend without errors (hang or freeze the system)
#Fist we have to pick the devices to bind and unbind. To select them we have
#to do a command:
#  ls -la /sys/bus/pci/drivers/ehci_hcd/
#And pick the devices that have this style: "XXXX:XX:XX.X" For example in this case
#are: "0000:00:1a.0" and "0000:00:1d.0". After this we have to put for each one selected 
#an unbind and bind, like in the case below, we see that for each one we have put in 
#hibernate/suspend and resme/thaw
#
# THIS FILE NEEDS EXEC PERMISSION (chmod a+x...)
#Also if we want to use hibernate for example with grub we have to add the "resume" option
#in this way: resume=/path/to/swap/partition
#for example:
#             title Slackware Linux
#             root (hd0,2)
#             kernel /boot/vmlinuz root=/dev/sda3 resume=/dev/sda9 vga=773 ro
#
#Commands to suspend/hibernate (You have to be root):
#   suspend: pm-suspend
#   Hibernate: pm-hibernate
#
#Or if you have upower (better and you don't have to be root) us the scripts(https://gist.github.com/1047799)
