No, that assumption is wrong.
Not sure about ATI technology, but nVidia Optimus is CHIP w/o any
video output, just PCI interface. It's writing resulting image into host
memory. Then host video output controller can be set to draw that
frame to any of outputs (VGA/HDMI/Composite/etc). If host has own
2D/3D unit it can draw to separate memory, but can be set to merge
both output (like PIP in TV)
Will try to do some ASCII art for that :)

huh, looks cute :)
So, any 2D or 3D unit can draw to any mem region (framebuffer), and any of
output controllers can read from any mem region.
