Its been a busy week.
In the past week, there have been three separate putbacks:
1) Kerry Shut putback a fix for audiohd to suspend/resume
2) Brian Xu putback a fix for iwk to suspend/resume
3) Judy Chen putback a fix for ath to suspend/resume
The upshot of this is, if you have a laptop with an Nvidia graphics card, its a fair chance that your laptop will support suspend (and resume!)
A big thanks to everyone who's been working on this.
