[tlinux-users:08671] Tecra M7 Autorotate

I've had a Tecra M7 tablet for a year now, and I'm thinking now that
I've worked out the fingerprint reader, it's high time I went about
getting the screen to rotate.  Fellow tablet users and developers are
welcome to join in or follow along ^_^

Based on prelimary research on Ubuntu, the ACPI seems to be exposing
three LID events: one for closing the LCD, one for opening the LCD,
and one for moving the LCD from tablet mode to normal laptop mode.
Missing is the opposite of that last one.  I'm guessing this prevents
the system from interpreting an a conversion event as a lid close and
turning off the display.

This works in windows, so I'm curious how it's done there.  A friend
suggested there was an accelerometer in the LCD panel that the windows
drivers were monitoring to rotate.  One (bad) way to do this might be
to check if the display is on, and the lid button in the closed state.
 Another might be to figure out how to expose the missing ACPI event,
and deal with a way of detecting orientation.

Anyone else have ideas?
