I am not sure of this error. I would check if the kqemu module has been
modprobed before I start the VM.
I actually use the kvm module. You can use the qemu-kvm command prompt if
you have kvm_intel or kvm_amd modules.

When you boot the VM, press ctrl+alt+2 to get to the qemu prompt. At the
(qemu) prompt type info and you will get all possible commands.

Are you using a 64 bit version of Debian. Virtualbox gets installed by force
on a 64bit OS, however, to get it working it requires 32 bit shared
libraries, my fedora has similar 64 bit one's so I was not able to use
Virtualbox and I could not locate all the packages required to facilitate
the 32bit support. One thing I am going to try is, to install a rhel4 on a
VM and the install vbox on that rhel4 and then copy over the libraries to my
host system. That may work.
