Your patch does work on my system, but... no, I don't think it means anything
if the inputs are inverted or not.  The BIOS might set the inputs to inverted
if the VID signals are inverted by hardware... which I would not consider to
be unusual or unexpected.

Of course, it might just as well leave them *not* inverted *despite* that
they are inverted in hardware... which suggests a new module option if anyone
ever discovers such a board.

BTW: I tested by applying your current quilt stack (up to and including the
improve-gpio5-test patch) to 2.6.15-rc2.
