ok, so if I run it in xorg, it suspends/resumes fine. if it's done in vt (with
i915kms loaded), then the display stays black upon resume.

Bug ID: 208729
   Summary: [i915kms] backlight on X230 (ivybridge) doesn't come
on after resume
   Product: Base System
   Version: 11.0-CURRENT
  Hardware: Any
OS: Any
Status: New
  Severity: Affects Only Me
  Priority: ---
 Component: kern
  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: adr...@freebsd.org

hiya,

I have a Lenovo X230 (ivybridge) which works fine on -HEAD now but the
backlight doesn't come on after resume. The laptop itself is fine though.
Brightness controls work fine until suspend/resume. The laptop resumes okay and
I can type reboot, ssh into it, etc fine.

This worked before the big haswell import.

r297693 definitely doesn't work. :(

I'll try some earlier kernels to see if I can pinpoint when things broke.
