I have tried Sabayon, Mint, Ubuntu, Xubuntu, Fedora, Crunchbang and none gave a smooth desktop experience on that machine for kids. Regards to the CPU usage, no matter what software being used (CMUS, Audacity, DeadBeef, GNOME player, VLC, etc). Note that this behavior happens on Windows XP and Windows Media Player too.
In conclusion, when installing modern software on ancient hardware and expecting them to run smoothly, you should be quite ballsy or willing to torture somebody.

Now you are hoping to run VLC and play HD videos too on these old farts?
The best use that I have found for that box is a headless (home) FTP server and download manager.

I've ran openbox, KDE3, e16 etc... on my transmeta crusoe its much slower than your P3 but it still runs fine and though it pegs the CPU alot it doesn't stick there once things are done processing and it play's mp3s and FLAC fine and small avi's okish.

You realize that more software than just KDE is using Qt?

Backwards compatibility is a good thing, but it also slows down progress.
Anyway, here we are talking about a change in default compiling options, and as was already mentioned, people with non SSE2 CPUs can just recompile, or use a distro that compiles the package without SSE2. Just because Qt decides to use SSE2 by default,it doesn't mean the distributions have to follow upstream.
