Lenovo X230 - suspend/resume video issues

[Adrian Chadd]

Hiya,

I have an Lenovo Thinkpad X230 running FreeBSD-10. I'd like some help
in sorting out the following issues:

* the ACPI and IBM sysctls for twiddling the LCD brightness don't at all work
* The backlight comes on during resume, but the video definitely doesn't
* I'm still investigating whether xorg actually comes back from resume
(and it's a video problem) or whether it hangs on resume.

The files are here:

Thanks!
