Can you hook up a serial line, or better yet, a serial console?
Logging to the serial port is nearly all the way to power-off, and
early in power-on. And the serial console starts pretty early as
well.
And I will see about getting a debugging page (or maybe even a wiki)
started.

You can bemoan, but it may not help at all. I keep hearing that the
open source driver works, but I don't think there has been success
yet.
