https://launchpad.net/~bderzhavets/+archive/lib-usbredir73 does resolve the blank screen problem, I can start my Windows7 guest with both VGA and QXL drivers using KVM-SPICE.
However when using QXL Windows hangs during startup. I tried using both 32 and 64mb VRAM for the QXL driver to no avail. This is likely a separate issue though.
