I built a plain -current USB stick image a while back and had no trouble, when using the HDMI output. I don't recall the revision at the moment, but will try again soon. Serial console won't work because the UARTs are not quite 16550-compatible. We do need a GetMemoryMap() / ExitBootServices() retry though.
