Thanks for your comments. I'll probably submit a proposal for both
pieces you broke it into, although I'd lean towards the graphics
hotplugging (specifically writing patches to add the necessary new
hooks to the porting layer, as well as patches to implement the hooks
in the xfree86 backend). If I end up with time left in the summer
after implementing the hooks, then I'd work implementing the udev
