Hmm, my winxp 32 guest is reproducing as well. And I can reproduce with just
the windows 7 media (mine is ultimate N, came off MSDN years ago):

~/src/qemu/x86_64-softmmu/qemu-system-x86_64 -m 512 -sdl -cdrom
/mnt/data/devel/media/win7_64.iso -boot d -bios ~/src/seabios/out/bios.bin

vista and windows 8 preview media are reproducing for me too.

Maybe it's a toolchain thing, anyone else on Fedora 19 that can independently
confirm?

I'll probably need some hand holding through that, I can't tell from looking
at the patch what parts are independent.
