Actually it stopped working starting with XFree86 4.0.0. The reason is 
that before it was possible to force X to think it has less framebuffer 
memory then is actually available and use the remaining piece for xatitv.

You might be able to hack the current driver (of any X version) to achieve 
the same result.

Also, newer X drivers know about overlay (which is used to display TV 
picture) and reset it occasionally - also something to be bypassed.
