I can confirm the last kernel upgrade fixed the suspend problem for me in
my inspiron 1525. Functionality is not fully restored yet, since the
options I pick in the power settings panel are completely ignored (ie when
I choose "do nothing when the lid is closed" the computer still goes into
hibernation), but that is a problem I can live with.
