It would be nice to support VIA C3 and C7 Padlock encryption hardware acceleration which is fully opensourced:

This CPU’s are fully x86 and used in cheap MiniITX moterboards. Some are completely passive cooled and have 2 Ethernet ports built in — ideal for budget boxes with Zeroshell.
Padlock support is built into recent Linux kernels and requires OpenSSL patching to add Padlock crypto engine, details here:
