They just phased it out, primary development of QEMU is done on Linux and there is more interest in "KVM" and kqemu was never really supported on 64-bit systems.
QEMU itself has improved in performance using "TCG", which translates emulated opcodes into native ones "on-the-fly" at runtime.
Sadly though, QEMU developers tend to break QEMU portability quite often.. up until recently the port was frozen at 0.9.x, and even now it's prone to segfaults and general unpleasantness.
VirtualBox is a joke, on systems without hardware virtualization features it mangles registers.. inaccurately emulating an x86, OpenBSD developers have reported this problem, Sun/Oracle aren't interested in fixing it.
