Nope... A fluke... Mostly...

FWIW the sound & networking appear to run fine for a while after 
resuming. But I just started a DVD. It ran fine for about 30 seconds and 
then the sound went. About 30 seconds later the video froze and the app 
(xine) has frozen also. (kill -9 time...).

restarting xine it runs the viodeo for about 10 secs before freezing 
again... With no sound...

The ethernet does still work though... Maybe it's fixed half the problem...

dmesg shows no errors...
