Assuming fglrx supports it, all you need to do is set up a virtual
desktop.  Add this line to the display subsection of the screen
section of your X config:
Virtual xres yres
e.g.,
virtual 1920 1024
etc.
This will allocate a large framebuffer and the crtc will be a smaller
window that looks into and moves around the bigger framebuffer.
