Yes, the updated radeon driver in 2.6.3-rc3-mm1 fixed this for me. 
Unfortunately the video acceleration doesn't appear to work quite right yet, 
but at least it comes back to life now ;)

Hey, sounds good! I'll check it out.

So e1000 survives S3 with your kernel? I may have to investigate further; I 
don't use the wired Ethernet much.

It sounds like madwifi is going to be usable quite soon, but I don't have time 
to hack on it myself and I need it to work now. Using DriverLoader makes me 
feel doubly dirty, because not only does it use the binary Windows driver, 
but there is there an open alternative ("ndiswrapper").

That was exactly my plan. The lack of event reporting on wakeup scuppered it, 
though ;(

You have S4 working, then? Lucky boy ;) I've not been brave enough to try S4 
out. Battery life in S3 seems to be pretty good, so it's not really necessary 
for me.

Thanks for your tips!
