rijndael isn't (yet) optional as it is required by ipsec and wlan code.
We just miss the dependency for the encrypted swap functionality.

Here is a patch that makes encrypted swap (but not rijndael) optional:

http://ftp.netbsd.org/pub/NetBSD/misc/mlelstv/uvm_swap.diff

which might be useful to create small kernels (it's just about 16kB).

Otherwise you could just add the dependency to uvm unconditionally.
