QEMU output with SeaBIOS 1.9.0 and above:

Yes. Tested it with the default version (1.7.2.2) of my distribution, 1.8.0, 1.8.1 and version 1.8.2.
Booting from ISO works with all versions.
Thanks, Johannes

It appears the fault is occurring in the OS bootloader, not in the SeaBIOS code.

It's odd that it works with a different SeaBIOS version. You could try bisecting between 1.8.0 and 1.9.2 to see what change the crash starts at - but be aware that random differences in the SeaBIOS binary might be tickling the underlying issue.
You could also try reporting to the kvm list - they'll know how to interpret the cpu dump.

I second this, but the root cause is that you need a new kernel or a new processor. Your processor doesn't know how to run code running in "big real mode" (you can see that you are in big real mode from the "ffffffff" in the dump on the lines between "ES" and "GS"). Your kernel has to emulate that code instruction by instruction, but it doesn't know how to emulate one particular instruction used by Windows, sahf. This instruction was added to kernel 3.13 in the following commit:
commit 98f73630f96f1a6d8c845b8b3e5f9ae532cf82d1 Author: Paolo Bonzini pbonzini@redhat.com Date: Thu Oct 31 11:19:42 2013 +0100
KVM: x86: emulate SAHF instruction
Yet another instruction that we fail to emulate, this time found in Windows 2008R2 32-bit.

You could also try reporting to the kvm list - they'll know how to interpret the cpu dump.
FWIW, the code dump disassembles to the following:
