Appears to be painfully sluggish under X (Raspberry Pi doesn't yet have graphics acceleration there, totally not your fault). Somewhat better under SDL on the framebuffer, but I keyboard input doesn't seem to be working there. I only gave this a really quick go and it's on a wheezy rootfs I prepared, but running a rather old version of the RPi kernel. I'll delve into it in more detail later in the week.
