[Hampshire] QEMU / KVM

I've managed to get QEMU working on my rather slow VIA Esther (C7)
1200Mhz processor. Windows XP Pro does indeed work, but painfully
slowly. Ideally I want to try out something quicker such as KVM or
KQEMU. Do either work on a VIA CPU or do I need an Intel or AMD chip to
do this?

Thanks,

Simon
