The 5600 supports S3, but you can forget about using it in Linux at this
moment.  There are two problems at the moment, one specific and one
general.  

Problem one is that the sleep button is not enabled for wakeup, so you
can make the laptop go S3, but you can't wake it up.  It took me weeks
to figure this out.  The experiment ended with a BAD BAD hack to enable
the sleep button for a wakeup event and at least it showed some signs of
life.  The friendly Intel ACPI developers are aware of this problem and
will fix it.

Problem two is of course simply the fact that many drivers don't support
being waked up from S3 yet.  In addition, the information for waking up
a Radeon M7 (which is in the 5600) is not really available.  You can try
the trick Ole Rohne did and repost the Radeon, but this is kludge.

Search the acpi-devel list archives for details.
