I don't know if the openssl speed test picks up the crypto-
dev hardware automatically. But ssh/scp definitely does.
I have run several tests on my VIA C3 Nehemiah+RNG+ACE,
which accelerates AES encryption. When the padlock(4)
module is loaded (it contains the Nehemiah ACE support),
ssh/scp performance is roughly doubled. It's quite
noticeable when transfering large files.
Best regards

PS: I can provide some benchmark numbers if interested.
