I've been told that it was mostly excluded because the pristine source 
doesn't include cryptoloop and nobody had expressed much interest in the 
CryptoAPI.

I patched it into 2.4.24 a while back, but I've misplaced my patch. You may 
be able to find it in the uml-devel archives. Basically I just did the 
following:

- Apply a cryptoloop patch (I forget if I was using cryptoloop-jari or 
cryptoloop-hvr, it was whichever was larger at the time because the smaller 
one didn't behave well with encrypted swap).

- Apply a UML patch.

- Alter the arch/um config files to include the CryptoAPI and cryptoloop 
config options.

It seemed to work quite well at the time.

If you're not in any rush and don't want to do it yourself, e-mail me back. 
I'll probably be getting back to UML in a more serious way in a couple of 
weeks, at which point I'll do something similar for 2.4.25 (or whatever the 
latest 2.4 kernel with a stable UML patch is at the time).
