trying to ease maintaining also for end users and to follow Robby's
concerns, I've adapted the qemu slackbuild to build also qemu-kvm and
make a single package (by default, but there's a switch to disable
building it). it's an experiment I assembled very fast but seems to work
on my machines.

IMHO our merge
of the qemu-kvm SlackBuild into qemu SlackBuild is premature. It remains
the intention of the KVM Team to discontinue qemu-kvm once qemu properly
merges the code from kvm. The KVM Team doesn't believe they are there
yet so why do we? 

Stephan Hajnoczi: Should I use QEMU or KVM? [1] see
the section: "What is the difference between qemu.git and qemu-kvm.git?"

I recommend continued support of the qemu-kvm SlackBuild with focus on
the x86 Intel, x86 AMD CPUs however the PowerPC and S390 CPUs should not
be forgotten. All other qemu CPU emulation should be directed to the
qemu SlackBuild until such time as the KVM Team says qemu-kvm is

Processor Support - KVM [2] 

It's a complicated issue. I
hope I'm still tracking properly.
