Sorry, that's wrong... from the X docs:
6. Driver Options

    "linear" - linear framebuffer mode (default)
    "no_linear" - banked framebuffer mode
    "no_accel" - software rendering only
    "hw_cursor" - hardware cursor requested (default)
    "sw_cursor" - software cursor only
    "mmio" - use I/O space via memory map (default)
    "no_mmio" - use I/O space directly
    "intern_disp" - enable internal display (default)
    "extern_disp" - enable external display
    "no_stretch" - disable stretching of lower resolution modes on panel
    "lcd_center" - center lower resolution modes on panel

This is for the NeoMaigc chipsets. I couldn't get it to work externally
until I added the extern_disp option.

It may be different for other chipsets, but the software can change the
display used.
