TDE and Wheezy

I am just about to install Debian and TDE on my husband's birthday present box. He is quite clear that he wants Squeeze. He likes stability and would rather have a reinstallation in the not too distant future than have something not called Stable. And he hates change! But not even the prospect of being left in peace far longer could tempt him into Wheezy. Moreover, he is adamant that he likes KDE 3 best. (I have given him various environments to try.) BUT - I'm the one doing it! If I can present him with a stable box, even if not a Stable one, he will be happy. So - how stable is Wheezy with TDE 3.5.14 nightly builds? I get the impression not quite. But using Squeeze means opening the box and putting an extra network card in in order to be able to install it. (Or anything else with a kernel < 2.6.34.) I just want to be quite sure in my mind that Wheezy won't yet do, before I start opening boxen. Thanks . Lisi
