Just in case you didn't notice: the latest Ubuntu version is 9.10, not 
9.04.

Someone explained it on the German list some time ago: While you are 
running 8.04 enter the command

sudo dpkg --get-selections > packages.list

in a terminal. It saves a list of installed packages in the file 
packages.list in your home directory. Move that file to a location which 
isn't overwritten by the new installation (e.g. USB stick). After 
installing the new system, copy the file back to your home directory and 
use the commands

sudo dpkg --set-selections < packages.list
sudo aptitude update
sudo aptitude upgrade

in a terminal. And please note: I didn't try this myself because I 
prefer upgrades instead of new installs.
