Win2003/Win2k8 R2: ACPI\QEMU\VGID driver missing

[jaceqp]

Hi there...
I've installed some Win2003/Win2008R2 VMs and have same issue.
I got pretty much all virtio drivers installed and running (Ballooning, Qemu Agent etc.) - yet still got one annoying "unknown device" (device ID: "ACPI\QEMU\VGID") on device manager list.
I already tried multiple virtio driver isos (0.1.101, 0.1.141, 0.1.160), but so far no luck.

VM's are created with basic VIRTIO SCSI, Qemu Agent, Ballooning and ACPI support on.

PM: 5.3-2 / 5.3-8

Any ideas?
