I thought maybe a newer kernel would help, so I tried 2.6.24-rc6:

# qemu-system-x86_64 -hda /home/uml/BusyBox-1.5.0-amd64-root_fs -m 384
- -nographic -cpu qemu64 -kernel /boot/vmlinuz-2.6.24-rc6 -append
"earlyprintk=serial,115200"

Am I being unlucky, doing something wrong or do you need a more specific
configuration to get kvm working?
