This is how I would approach it:
1) Look at the custom board's .dts file
and make sure it has a crypto section with properties
which match those in arch/powerpc/boot/dts/mpc8548cds.dts
from 2.6.27.18.
2) talitos in 2.6.27.18 implements only ESP IPsec algorithms.
So if you need h/w accelerated plain cipher or digest
algorithms,there are not there.
3) If IPsec is what you are interested in using, talitos implements
aes-cbc and 3des-cbc encryption, and hmac-sha1 & -sha256
& -md5 authentication. You can try it in 2.6.27.18.
Turn on the necessary CRYPTO kernel options as well
as applicable IPsec options.
4) For better IPsec performance, add the talitos patches made since
2.6.27 which are in the mainline kernel tree.
(Linux 2.6.29-rc8 includes 7 extra patches).
These could be added to 2.6.27.18 easily.
