OK, here's another go.

1. Download Pacifist and open the Safari 3.2.3.dmg
2. Look in the Resources tab and look for a file called Payload
3. Extract "Payload" to your desktop and unzip it, it won't show up as
zip but you should be able to unzip it. If not, press Enter and
add .zip to it and save it with the .zip extension.
4. After unzipping the "Payload" folder you'll need to replace the
files in the folders in the exact area on your system. So you navigate
to one of the folders and only erase what is in the "Payload" and
replace the "Payload" version of that file to where you erased it
from, and so on until all your "Payload" files have been put into the
system to their respective places.
5. Repair you disk permissions and reboot your machine.
6. Run Safari 3.2.3 installer and it should run without having to ask
you where it will be installed.
7. After the installer finishes, you'll need to reboot.
8. Enjoy, there's nothing wrong with 4 but I don't think it's quite
ready yet. For me it seems to be crashing from page to page. It looks
like some sort of memory problem. But 3.2.3 is working fine and has
been.

Re Tiger:
To me it looks like the Tiger version of the Safari 3.2.3 package has
the application listed directly in the Package Contents tab of
Pacifist unlike the leopard version. This is good for those who wish
to completely downgrade from Safari 4 and leave no trace of it on
their machines. Those wishing to do this should be able to select the
package in Pacifist and click the install button in the toolbar. This
will replace the Safari 4 files in the /System/Library and the /usr
directory with the Safari 3 versions. If you want to run side by side
installs, you simply select Safari.app from the Applications directory
in the Package Contents tab and click extract, placing the application
wherever you like. When that is finished, just follow the directions
from earlier in this thread to modify the Info.plist file and correct
the preferences issue.

More for Tiger:
Thanks for all the info here. I'm using Tiger so the Pacifist process
was a lot simpler for me. I had manually deleted all files I could
find related to Safari 4, but still couldn't install the older
version. Extracted/installed 'Safari.app' using Pacificist and now I'm
back in 3.2.3 heaven.

I'm using Tiger and it was very easy to do the update using Pacifist.
After opening Safari 3.2.3 in Pacifist all I had to do was select the
Package Contents of 3.2.3 under the Pacifist "Package Contents" tab
and then click install in Pacifist. I was not interested in a side by
side with S4. S4 is gone.
