Bug Description
qemu.git (memory/queue branch) commit: 6cc7686696f73ae
or qemu.git (master branch) commit: 8843cf40c0f4829
kvm.git commit: 7f914d61cd2156e
64-bit Windows guest cannot boot up, but 32-bit windows guest can boot up successfully. For Win7, it will show blue scream of death when booting up. For Windows XP, the guest hangs without blue screen when booting up. But when I use qemu-kvm.git with commit a040d28b, I won't meet this issue. I did the comparative test in the same box and using the same command line to create a guest.
I found this bug in memory/queue branch of qemu.git on September 21st. As some codes in memory branch were merged into master branch, the master tree of qemu.git also has this issue now.
I found the following git log in master tree. And that merger maybe introduced this issue in master tree.

Reproduce steps:

I used the default 'memory/queue' branch when I filed this bug.
The master tree doesn't have this bug.
