Just gave it a spin, breaks booting a Windows 7 VM for me. Using qemu-1.4.2
from Fedora 19 as well as qemu.git.
Here's the BSOD (F19 qemu and seabios 1.7.3):

I bisected to:
commit 76e58028d28e78431f9de3cee0b3c88d807fa39d
Author: Kevin O'Connor <kevin at koconnor.net>
Date: Wed Mar 6 21:50:09 2013 -0500
acpi: Eliminate BDAT parameter passing to DSDT code.
Reproducing command line:
x86_64-softmmu/qemu-system-x86_64 \
-bios /usr/share/seabios/bios.bin \
-machine pc-i440fx-1.4,accel=kvm,usb=off \
-m 4096 -smp 4 \
-sdl -vga std \
win7.qcow2
Let me know if there's any more info I can provide.
Thanks,
Cole
