Well, TOSHIBA provide some documentation for their own BIOS (HCI/SCI
specs, etc.)
but attempts for getting more documentation (specially for PHOENIX
bases laptops)
is scarse or almost null.
As far as I know the author of the omnibook module got some info that
he used to add support
for some models with PHOENIX BIOS, but they haven't provided any documentation
for newer models (yet, or as far as I know).

For the GPU fan, I'm almost clueless, since this is the first time
that I have a TOSHIBA
laptop with nVIDIA card and the fan seem to be running ok (my card is
a 8700). In that
aspect, I'm not sure if that part belongs to the nVIDIA binary drivers
or the omnibook
(or any other) driver itself

Indeed, more documentation could be useful, the support I added to the
X205 is partial,
I still have some issues with hotkeys and/or multimedia buttons, but
its a start, maybe I'm
doing something wrong or who knows.
