I managed to unpack the existing initramfs, add the twofish modules and repack 
it. Now I don't know how they are supposed to be loaded (there is no 
/etc/modules). For now I just put two modprobes into the init-script between 
pre-udev and udevd, which works, but is rather hacky. Does anyone know a 
better way?

In a way I did exactly that, works, exept for the missing twofish modules in 
the initramfs.

Will look into that.
