Hi all,

Yesterday I bought a VIA Nehemiah box, partly because of its AES logic. It 
seems that OpenSSL with Padlock support has been imported in netbsd-4
and head, but I am running NetBSD 3.1 on this machine.

The attached (trivial) patch adds Padlock support from OpenSSL 0.9.8d to 
OpenSSL in NetBSD 3.1. Maybe it's useful to others too :). The benchmarks 
give nice results:

---
$ openssl engine padlock
(padlock) VIA PadLock (no-RNG, ACE)

$ openssl speed -evp aes-256-cbc
