Comment 3 for bug 99288

After some suspend/resume/power cycles, I'm no longer able to reproduce this, so I think it may be a power management issue rather than a straightforward regression in the driver. as such, it's less serious than I thought, and it's also difficult for me to test.

For now, I'm unsetting the milestone and lowering importance. If I can reproduce it in the future, I'll follow up here.
