Reading the Crypto FAQ out of the International Kernel Patch, I see 
this:

6) I get "Unsupported encryption type" when I use losetup or mount. 
What's wrong?  

You need a version of losetup and mount that understand new 
encryption types. To get it, you probably have to apply the util-
linux patch you can find in linux/Documentation/crypto and rebuild 
mount and losetup.  

I was reading the actual patch, so it was tough going - but it looks 
like only losetup and mount are affected.  There appear to be two 
patches - one for crypto, and one that allows the programs to ask for 
the encryption key.

The patch is available at http://www.kerneli.org/ - I'll try it 
against 2.2.17 sometime soon.
