One thing I suspect is that the kernel side of kvm had an issue around
this time (Ubuntu 9.10) with a bios.bin larger than 256kb.

With qemu 0.14.0, you could investigate what value is being used for
identity_base in target-i386/kvm.c:kvm_arch_init.
(Notice it will be a lower value if KVM_CAP_SET_IDENTITY_MAP_ADDR is
defined, and this will allow for a larger bios.bin.)

I think I was able to use OVMF X64 with kvm on Ubuntu 10.04, but I
don't have a system set up right now to verify this.  I am able to use
OVMF X64 with kvm on Ubuntu 10.10.
