the disk is fine, I can boot it natively. The hardware emulation in qemu is very old (circa Pentium Pro CPUs). It's possible (probable, do I remember LBA supports 120 Gbytes? wasn't there an earlier max of 32 Gbytes?) the disk (320 Gbytes) is larger than the emulation supports.
Ah, I haven't tried very large disks. I'll check it out.
You were right, it was missing LBA48 support. I added it for kvm-59 (by coincidence, an LBA48 patch was posted for Xen four hours ago; so I used that).
I now have Windows happily installing into a 300GB virtual disk.
