kqemu is what you want.

A quick comparison table, for the record:

* kqemu runs on any CPU; KVM requires a CPU with the virtualisation
extensions (VT for Intel, AMD-V for AMD chips)

* kqemu runs with standard qemu; KVM needs its own qemu from the KVM
project

* kqemu can only accelerate userspace code; KVM will do both
userspace and kernel code

* both kqemu and KVM run as modules in the host kernel
