NASM (in the ports) supports the older ones, but not the newer
ones supported by the Athlon/K7. I sent patches to the author
to support those, too, but nothing happened.

Well, when I added 3DNow support to the Seti@home client, I
assembled the 3DNow instructions "manually", i.e. I created
small gas macros for that purpose. It's ugly, but it works.
The 3DNow specification (with instruction codes) is available
from www.amd.com.
