If you load cryptodev.ko and have a card, you will be able to make use
of the accelerator card... depending upon how much you are willing to
pay will determine the performance...

For example, the hifn mini-pci card w/ a 7954 that is readily available
will only do 128bit AES at 19Mbps (bits), so that'd be slower than what
you're seeing now...

I have not been able to find a card that is >100Mbps that isn't the cost
of a complete new computer...  Though I'd be willing to be proven wrong..
