Running SuSE 10.3 on a Lenovo Thinkpad z61p after upgrading from SuSE 10.2 and alls working well except suspend. I am running the ATI driver that worked properly under SuSE 10.2.  

When I press Fn+F4 to suspend, the screen goes very dark/brownish shades of everything and then properly suspends.  On resume, it comes back up properly but the very dark brownish shades exsist over everything.  I can still work with the windows, etc just as normal but everything is very dark/brown.

So first, had to add the s3bios to kernel parameters in grub and to the /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-lenvo.fdi file.  I also had to put z61p in for the hardware version as well:

---snip----
     <!-- T60*, Z61* -->
      <match key="system.hardware.version" prefix="ThinkPad ">
        <match key="system.hardware.version" suffix="T60">
          <merge key="power_management.quirk.s3_bios" type="bool">true</merge>
          <merge key="power_management.quirk.s3_mode" type="bool">true</merge>
        </match>
        <match key="system.hardware.version" contains_outof="T60p;Z61m;Z61p;Z61t;Z60m">
          <merge key="power_management.quirk.s3_bios" type="bool">true</merge>
          <merge key="power_management.quirk.s3_mode" type="bool">true</merge>
        </match>
      </match>
---snip---

So doing that got the suspend to work properly, etc when executing pm-suspend.  There is no darkening of the screen on resume, etc.  

Digging through the logs, I realized it was the gnome-power-manager which was executing the suspend.  I executed this from the command line and got these results:

:~> gnome-power-cmd.sh suspend
Suspending
Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

and right away after executing the command the screen went brown/dark and remained that way after the suspend/resume cycle.

If I log out and back in without restarting X, the colors come back to normal.  I even tried to take a screenshot to show you what the dark/brown looks like, but the screenshot turned out normal colors.

This problem also seems to happen if I let my system sit idle for a while.  I suspect this is just the 15 minute timer I have set.  I have set this timeout to  never now so it should go away, but it'd still be nice to get my Fn-F4 shortcut back working again.
