"Free" Assembler And Emulator For The 68HC11/12?

V. asks: "Our local LUG is working on a roving webcam robot. In order to drive the motors we are planning to use a 68HC12 ucontroller. I've found some patches against an old release of gcc and egcs that will add support for this ucontroller but I don't think they are part of the normal gcc distribution. I'm wondering if anyone knows where I can find a Free(as in GPL) assembler and emu for the 68HC12 that aren't a pain to compile/install. I doubt there is anything apt-get-able but then again I really wouldn't know since the extent of my assembler and hardware experience is working with xspim for about a semester many moons ago."
