Hi, 

I tried to do so with a working kernel (2.6.24-1) and a non-working kernel 
(2.6.25-rc2) :

--------
$ ls -la /tmp/init-2.6.25/lib/modules/2.6.25-rc2-amd64/kernel/crypto/
total 93
drwxr-xr-x 2 didier didier  1024 2008-02-19 23:31 .
drwxr-xr-x 8 didier didier  1024 2008-02-19 23:31 ..
-rw-r--r-- 1 didier didier 33060 2008-02-19 23:31 aes_generic.ko
-rw-r--r-- 1 didier didier 11778 2008-02-19 23:31 cbc.ko
-rw-r--r-- 1 didier didier 25958 2008-02-19 23:31 crypto_blkcipher.ko
-rw-r--r-- 1 didier didier 16658 2008-02-19 23:31 sha256_generic.ko
$ ls -la /tmp/init-2.6.24/lib/modules/2.6.24-1-amd64/kernel/crypto/
total 80
drwxr-xr-x 2 didier didier  1024 2008-02-19 23:32 .
drwxr-xr-x 8 didier didier  1024 2008-02-19 23:32 ..
-rw-r--r-- 1 didier didier 30873 2008-02-19 23:32 aes_generic.ko
-rw-r--r-- 1 didier didier 15406 2008-02-19 23:32 blkcipher.ko
-rw-r--r-- 1 didier didier 11712 2008-02-19 23:32 cbc.ko
-rw-r--r-- 1 didier didier 15584 2008-02-19 23:32 sha256_generic.ko
--------

So it seems that the same modules are loaded on both initramfs'es..

Regards, 

Didier
