Kqemu actually works with svm emulation.

Have you tried -cpu qemu32,+svm? I think I only enabled svm on qemu64,  
because I'm not aware of 32-bit AMD CPUs that can do svm.

If you use -cpu qemu32 that also means you'll get an emulated Intel  
CPU. KVM-AMD will refuse there.

Also, back when I developed it, 32-bit kvm didn't really work  
properly. So please let me know what you find out!
