S3 w/Ubuntu 7.04 on a Dell Latitude D820 is pretty good, but not
perfect.  Sometimes wireless or something like that might not recover,
but its definitely good enough to configure the computer to suspend to
ram instead of crash or power-down if it runs out of batter while
unattended.  That way I don't loose the state of my apps.  Its also
good enough that I sometimes use it.   ...but since I don't fully
trust all devices to work correctly after a suspend, I normally power
it off.

I just (3 days ago) updated to Ubuntu 7.10 and it is at least as good.
 I haven't tested it enough to know if it is better or not.

Cheers!
Ty
