Just finished performing the operation, so I wanted to summarize for everyone. It appears to work great! The only things it missed were stuff that was installed outside the normal workflow, like Picasa.

0) since this is Ubuntu I'm talking about, I'm using my Ubuntu One account as the place to store the work file, so it'll be right there after the install:

cd ~/Ubuntu\ One

1) before doing the fresh install:

sudo dpkg --get-selections > installed-pkgs.txt

2) perform the installation, and then:

cd ~/Ubuntu\ One sudo dpkg --set-selections < installed-pkgs.txt sudo apt-get dselect-upgrade

3) go do something else for a while :-) (actually there were a few packages that required user input to finish)

I'm preparing to actually do this now...just to see what that grep catches I tried it reversed:

ak@mfj:~$ sudo dpkg --get-selections | grep -i kernel kerneloops-daemon install nfs-kernel-server install nvidia-173-kernel-source install nvidia-kernel-common deinstall vmware-player-kernel-modules-2.6.17-11 deinstall vmware-player-kernel-modules-2.6.20-15 deinstall vmware-player-kernel-modules-2.6.20-16 deinstall ak@mfj:~$

Given that most of this isn't the kernel itself I'm going to leave these things in. (even though it gets me a triple helping of vmware)

So like this?....

1. before doing the fresh install:

sudo dpkg --get-selections | grep -vi kernel > installed-pkgs.txt

2. Backup the file, install new system then:

sudo dpkg --set-selections < installed-pkgs.txt sudo apt-get dselect-upgrade

Just wanna get one succinct recipe for posterity. :-)

I'd leave out the "|grep -vi kernel" part, but yes, that's correct.
