This server this site is running on has a VIA CPUwith PadLock features enabled. That allows fast hardware accelerated encryption, namely AES, SHA1, SHA256. With modern kernel and openssl, there is no special patch needed. However, some application using encryption still need a patch to use the hardware feature.
If you are running a PadLock enabled Via CPU, this page has a list of patches for various linux programs. Look at the bottom of the page for contributions, and see if you're using any of these software. Even if you are using the same version, I recommend you to check if the patch hasn't been already applied by the maintainers of your linux distribution.
I applied the patchs for openssh, lighthttpd and a couple of other software.
