You are right Alan!

Found that in the official AMD documentation, too. It was a communication
problem. I received the hint for playing with 'movntq' on the Athlon from a
friend. He named it 'movqnta' which is obviously wrong...

So I've checked it yesterday, again.

Now, I've did a string search over as

SunWave1>as -v
GNU assembler version 2.9.5 (i686-pc-linux) using BFD version

All 'new' Athlon/Duron instructions are supported!

Thank you very much and my apologies for wasting your time.
