How do you do dual boot without Dual activation for CS3?

Question

I know this has been discussed but I can't find the post called Daryl Pritchard, "Activating CS3 with both Vista and XP Pro on same system" #3, 21 May 2007 12:49 am .  That link seems to be dead.
I'm slow to make the switch, but I'm planning to install Vista on the same box I've had XP Pro on.  I have a LOT of software on this box (it normally takes 34 hours to install everything from scratch) including VIsual Studio (2003, 2005, 2008), Lotus Notes designer (R6.5, R8), 3D Studio Max, etc. etc. etc.  I'm not ready to flip the switch and just run the Vista upgrade.  I want to dual boot with XP on one partition and Vista on the other, so that I can boot to XP if something doesn't seem to be running correctly under Vista.
Here is my dilemna.  I also have Photoshop CS3 installed on my laptop, and I need it there because I travel every few weeks and still have to manipulate images.  I'd like to avoid deactivating licenses everytime I get on a plane or drive across town.  I don't want to have to use up both of my "activations" when I'm staying within the intent of the Eula - it's only going to be used on one machine.
How has everyone else faced this challenge?  I know there are plenty of people with dual boot set ups.
I'll deactivate Photoshop on XP Pro if I have to, but that's going to be a headache if I have to turn on the laptop everytime I work in XP on the desktop and need to modify a PSD image.

I believe you can only deactivate/activate 20 times, precisely to keep
people from swapping the two licenses amongst more than 2 computers, so
deactivating on your travel-computer will only work for the next few times
you do it.
Depending on what things you do to your images, you might be able to get by
with using Elements to work with the PSDs.  The newer versions of Elements
lets you work with Layers so it may be ok.  Install the PSE trial and see
how well it works.
If you must have Photoshop, and one copy needs to be on your laptop, then
you must choose dual-boot you want to use it on, and perhaps install the
trial on the other bootable partition and if it works fine for everything,
and at the end of 30-days, choose which one to keep activated, or decide
that you can upgrade your XP.  I think you should attempt to upgrade it,
anyway, just to see if it's even possible.   I think you can uninstall the
upgrade if you do it right away, and get back to your XP...I had to do that
when my graphics card refused to work, even though the Vista Upgrade Advisor
didn't complain.  Installing Vista from scratch seemed to work.  I just
bought a new HD and reinstalled everything.
Another thing to consider is that Windows 7 will be available for retail
purchase before Halloween and people like it better than Vista as far as
running things faster, so maybe just skip Vista.  The only glitch I had was
having to uninstall Nero's packet-writing (CDRW as a floppy) software after
I upgraded to Vista and it didn't quite work and I had to use a Nero-clean
utility to get rid of it.  It isn't compatible with Win7 and I could have
gotten around the problem by merely uninstalling Nero before upgrading and
putting it back, afterwards.  I have an older version of Nero was my actual
problem.
I am running the Win 7 Ultimate RTM from my MSDN subscription and like it a
lot...more transparency and they finally combined the quick-links with the
actual task-bar so you can just pin things down there and they are
highlighted if they're running or not highlighted if not--sort of like a Mac
has been doing for a while, but with much smaller icons if you want.
