 I thought the latest kvm-userspace snapshot should contain a reasonable
good snapshot of qemu, but I was wrong. Somehow kvm managed it to break
the support for -acpitable.

I checked out the latest qemu trunk and now -acpitable works great. Thanks!

But qemu is slow, with -enable-kvm it's also slow .... I think I will
try out kqemu.

Thanks for you patience! I should have checked if plain qemu works ...
