Not on this laptop, no.
I've observed that problem with TV-out connections on the 945 chipset of
an Atom board (the D945GSEJT), though, which managed to think it had an
LVDS connection despite not having that connection even wired up. It
didn't change to a dual-display configuration, but it did cause some
suboptimal randr configurations that went away by forcibly disabling the
LVDS output.
