Did I read correctly that some 3DNow instructions cause latency issues?

I used line-in. The latency program locked up the box during its run
with the default settings. In fact in nonblock mode (I presume that's
default) the audio sounds horrible with all sorts of aliasing effects.
# latency -m 128 -M 128 -b
...sounded ok, xruns.. I could not get the rate above 29337 without
immediately bombing out with an xrun (around frame 512).
