Manual and options for the "modesetting" driver

[Stefan Monnier]

I'm trying to use the "modesetting" driver for a dual-monitor setup
using a displaylink adapter and a Poulsbo card, and where the monitors
are rotated and where I only want 16bpp.

The only part I managed to get is an output on my Poulsbo-connected
monitor, but all the other things I specified in my xorg.conf seem to be
ignored, so: is there a manual somewhere listing the available options
(I've discovered "kmsdev" so far)?

FWIW, find appended my current attempt (which gives the same result as
a trivial xorg.conf that just says to use "modesetting").
