I'm going to also put in a vote for software based encryption
(dm-crypt).   I've been using it
on my laptop for several years now.    Even with a simple dual-core
CPU, the tests I did of
disk IO at the time didn't seem to show any significant change in
throughput.   On a quad (or higher)
core desktop, I would expect it to be even less notable.

Since this is an imposed requirement, I think the first question is:
What does the outside agency
find acceptable?   It may very well be that they will only accept
hardware or commercial software (i.e.
"certified") solutions.
