Qemu obviously fails to use the kvm kernel module because
the CPU specific kvm module (kvm_amd or kvm_intel) has
not been loaded. This has nothing to do with the qemu
command line (except that you could probably run qemu
slowly without the --enable-kvm option).
The reason for kvm_amd or kvm_intel not being loaded is
what you should look at.
Try to modprobe the right one (kvm_amd or kvm_intel)
manually, then look at the system log messages (from boot,
from your first attempt to run qemu --enable-kvm after
boot and from your modprobe attempt). Look for any
messages mentioning kvm, VT, svm, virtualization or
anything else that could explain this.
Also look at /proc/cpuinfo it should mention "svm" but
not "vmmcall" if it is an AMD CPU or "vmx", but not
"hypervisor" if it is an Intel CPU.
In your list of modules the only thing I can see that
looks suspicious is that you seem to have a number of
virtualbox modules and some other strange virtualization
drivers loaded that makes me suspect that there is
another virtualization program interfering with kvm use
of the CPU's virtualization features.

I always used "qemu -cdrom .... -enable-kvm -vnc :10 ....." in my
commands.
What do you mean by qemu scripts?
