update some of "why can't i suspend" section

------------------------------------------------------------------------------
  
  === Finding out why suspend or hibernate aren't offered ===
  
+ If g-p-m doesn't offer you a suspend or hibernate option then you can use the following commands to narrow down why. (The commands are shown for debugging suspend; for hibernate just replace all occurrences of "suspend" with "hibernate".)
+ 
+ Also see http://live.gnome.org/GnomePowerManager/FAQ#head-5d4d7bb306ca154c956e3ef69dae036942f6cf40
+ 
+ ==== Does the power management subsystem think you can suspend? ====
+ 
+ HAL:
+ 
+ {{{
+ dbus-send --session --print-reply --dest="org.freedesktop.PowerManagement" --type=method_call --reply-timeout=6000 /org/freedesktop/PowerManagement org.freedesktop.PowerManagement.CanSuspend
+ }}}
+ 
+ UPower:
+ 
+ {{{
+ dbus-send --system --print-reply --dest="org.freedesktop.UPower" --type=method_call --reply-timeout=6000 /org/freedesktop/UPower org.freedesktop.DBus.Properties.Get string:org.freedesktop.UPower string:CanSuspend
+ }}}
+ 
+ If this says "true" then the subsystem thinks you should be able to suspend and gnome-power-manager is just not displaying the option. If it says "false" then we need to work out why it thinks you can't.
+ 
+ ==== Further troubleshooting ====
