With the recently posted patches to if_iwn.c. I can finally reliably
suspend and resume my ThinkPad. Unfortunately, I also get a black
screen. However, this is with VESA on 9-STABLE, not kib's KMS
patches. Also, I have not had a chance to confirm whether USB works
after the resume. I'll try some display related sysctls and check out
USB when I get a chance.

FWIW, the display does not come back on whether I am in console mode or X.
