Sorry about that...  Brad, very well done!

On another note, I'm looking over the USB HID spec to better understand the boot-time device constraints. I doubt you can use an absolute coordinate tablet as a boot-time mouse that actually reports positions in absolute terms, but maybe it's possible. It's not a big deal, just cosmetic really - to be able to use the tablet at OS install/early boot time, before more complex drivers are loaded. I'm not sure how possible this is, but the USB HID spec seems to imply it.
