Ok I see what went wrong.
I accidentally had a XEN kernel still running so insmod did not work.
Now it works and the message disappeared.

But, kqemu is not much faster than qemu. I perceive about 1.5x over a 
1gbit network  to a terminal through an x session.
It is much much slower than win4lin, but it is free and
I can live with it under most applications except streaming.
Is there something I could have done wrong?

Server: Dual Opteron 1.6Ghz/16G SUN V20Z
Terminal:  Mac Mini 1.6GHz
Connected with 1Gbit network.
