How to use a terabyte of RAM

Those instructions seem to be for gnome, and I'm using kde (without 
kpowersave installed, which I'm reluctant to install due to the "ubuntu 
laptop disks eating themselves after 6 months if you don't "hdparm -B 
255 /dev/sda" them.  (See 
http://www.atomicmpc.com.au/forums.asp?s=2&c=16&t... for details.)

However, all I had to do was edit /etc/acpi/powerbtn.sh and replace the 
call to /usr/bin/dcop with a call to /etc/acpi/sleep.sh.

I'm aware this is probably not the _approved_ way of doing this, but as 
with most "chainsaw, shotgun, and duct tape" solutions, it works just 
fine for me...
