I can confirm this was introduced in:
commit e5ad936b0fd7dfd7fd7908be6f9f1ca88f63b96b
Author: Jan Kiszka <jan.kiszka@siemens.com>
Date: Fri Feb 17 18:31:19 2012 +0100
kvmvapic: Introduce TPR access optimization for Windows guests
For me, this results in a SEGV until:
commit bf75fec175d00885c7ae06e5917bde86110c386a
Merge: 9f1d43b 7e68075
Author: Anthony Liguori <aliguori@us.ibm.com>
Date: Fri Mar 9 12:29:55 2012 -0600
Merge remote-tracking branch 'qemu-kvm/uq/master' into staging
* qemu-kvm/uq/master:
kvm: fill in padding to help valgrind
kvm: x86: Add user space part for in-kernel i8254
kvm: Add kvm_has_pit_state2 helper
i8254: Open-code timer restore
i8254: Factor out base class for KVM reuse
Which then turns it into:

A simple test case to reproduce:
x86_64-softmmu/qemu-system-x86_64 -nographic -nodefconfig -enable-kvm
-nodefaults -kernel /boot/vmlinuz-2.6.32-29-generic
I've tried multiple guest kernel versions and they all reproduce (not surprising
since EIP is still in SeaBIOS here).
This also happens with the very latest SeaBIOS release.
