0.12.0-rc2 has some issues with WinXP.64 install.  It hangs early during
the install with trying to start Windows.  No further progress is made
and it chews 100% cpu. 

This seems to be kvm module version related.  On up-to-date Fedora 11.64
install 0.12.0-rc1 works, -rc2 doesn't  Git bisect between -rc1 and rc2
points to:

commit 066263f37701687c64af9d8825e3376d069ebfd4

cpuid: Fix multicore setup on Intel


Reverting this fixes the problem.

On older kvm modules (2.6.28 from Ubuntu Jaunty) I can't seem to find
any version of recent qemu that works with winxp.64 install.  Switching
to kvm-kmod packages:

2.6.32 modules work fine with 0.12.0-rc2, no issues at all

2.6.30 modules fail, reverting the above commit doesn't help, seems to
be in the same boat as 2.6.28 modules

2.6.31.5 (roughly equivalent to Fedora11 modules) work on -rc1, fail on
rc2, reverting above commit fixes -rc2.

Maybe some other folks are seeing this issue and we can track down what
the real issue is.
