I cross-checked it the other way, which really should have been done
at the very beginning instead of wasting so much time of so many
people at once.  I just tried qemu-kvm-1.0, which I wasn't due to
an unrelated issue (1.0 does not work for me in my funky 32/64bit
environment).  Also, since the bug has been reported especially
against 0.15 version (triggering by upgrading from 0.14 to 0.15),
I didn't insist on trying 1.0, which was my biggest mistake.

And in qemu-kvm-1.0, the problem guest Just Works.  So i t must be
something else which were fixed between 0.15 and 1.0.

Upstream qemu 1.0 does not have this issue too.

I'll try to verify this series in a moment, but hopefully it will work
fine too :)

Thanks!
