Summary: depmod reports loop in kvm.ko 

Initial Comment:
I am using slackware64-current with 2.6.30.1 kernel.  I compiled this kernel to get the latest ath9k, anyway depmod reports as follows:

The modules cannot be loaded and so when starting the VM i get:

bash-3.1# qemu-system-x86_64 hdd.img -m 1024 -smp 2 
open /dev/kvm: No such file or directory
Could not initialize KVM, will disable KVM support

My CPU is a phenom II 955 x4.  The VM actually boots and works but is slow.

Thank you in advance for any help you can give.
