Actually, the backlight was just off by default. There's also a bit of
lag when changing brightness in Ubuntu that wasn't there before the
firmware upgrade, and the EFI menu is garbled when booting a live image,
but the system works fine besides that. Will get back to some tests.

Title:
  8086:0166 [Lenovo G580 2189] Black screen without "nomodeset" boot
  option

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I recently updated the firmware on my Lenovo G580 (Bluetooth being
  broken with the old one), and now I can only boot 13.04 (installed as
  well as Live USB) with nomodeset enabled. Even with that option, I
  seem to be stuck on software rendering, can't change the screen
  brightness, and trying to switch to a VT only freezes the system on a
  solid gray screen, but I guess that's something for separate bug
  reports. GPUs: Intel HD 4000; Nvidia GT 635M (Optimus, normally
  unused).
