Looks like Windows 2000 (or at least ISO patched with HFSLIP) can handle virtio storage driver if you give it the floppy image during initial installation. It's a bit buggy, shows up as 8 identical disks instead of only one, but it works. Sadly, it's the only virtio driver that works; NetKVM and QXL throw error 31. I can still get full color by setting VM to use VMVGA adapter and extracting the video driver from VMware Tools installation wizard, but it's much more laggy.
