Hey Warner,

This is a great idea.  Would it be possible to provide a little more 
background about what the expected failure/success modes are?  If we had 
some easy to follow steps we could ask for testers on current@ and create 
a wiki with a list of known working/broken hardware.  That'd be a great 
step towards having widespread suspend/resume support.

Thanks,
Jeff
