Can you try the option '-no-kvm' both with kvm-57 and kvm-58?
-no-kvm works. I can hit this just booting a live CD both on a 32bit
and a 64bit host. It looks like compatibility with old kernels is
broken (the kvm package only contains the userspace bits, the kernel
bits come from the kernel which is currently 2.6.24-rc6). Building an
updated kernel module makes things start to work on my laptop
Right. I fixed this for kvm-60, see attached patch.

kvm: qemu: restore IO_MEM_ROM mark to bios when registering the memory with kvm
We removed the IO_MEM_ROM mark for qemu, since the tpr optimization needs to
update the bios. However, kvm_cpu_register_physical_memory() uses the mark
for other purposes, so keep it. The removal broke bootstrap on older kernels.
