I can confirm the same on my x220 (and this is a regression).  Switching
over to another ttyv and back "fixes" it as trasz@ noted.  I think the issue
isn't that the backlight isn't on; I think it's that the frame buffer contents
aren't restored properly and are left as all black when resuming on the
console.
