Does the crypto(9) framework recognize and use these instructions? Looks like the Windmere-series Xeons will drop into my system boards; I gain two cores per CPU at the same time, so I'll go from an 8-way SMP system to a 12-way one. I am considering spending the money to upgrade a couple of servers here that run geli-encrypted disks, as during heavy I/O they spend a LOT of their CPU time on the disk encryption. The differences I see in the use of TrueCrypt on Windows machines that have AES instructions .vs. those that do not are very significant and I'm curious if this carries over to FreeBSD.
