Placing it below the kernal ROM would be a good idea (see groepaz comment).

I've had a quick look at them and as far as I can tell they are using the ROM
routines for setting the pointers to the character and color RAM. So if you
update the kernal variables, it should work with the new video memory
location. This is untested however, and feedback is appreciated.
