There is now a hotkey_tablet_mode attribute, poll()/select()-capable, which
reports the current status of tablet/normal mode.  Extremely handy if you
happen to boot on tablet mode, etc.

It is on the devel branch of my git tree.  I will send out a new
thinkpad-acpi test release soon.

Thanks, it confirms that HTAB is the tablet/normal hardware switch, I'd
guess HDIM is either a LED, or something that rotates the screen in
hardware, or some other behaviour-modifier for the EC (maybe it
enables/disables the touchscreen or somesuch?).  You could try playing with
it using the ecdump write interface if you are curious on what it does (I
have run out of time to mess with that right now).  The source code has a
comment that teaches how to use it.
