swsusp broken

["Mika Penttilä" <mika.penttila@kolumbus.fi>]

2.6.0-test4 software suspend seems to be badly broken...looking at it 
(relevant code included below), no wonder. pm_suspend_disk() calls 
swsusp_save(), which is is essentially a nop. The intention was clearly 
that after resume control would return from swsusp_save(), which isn't 
the case, instead we return from swsusp_write(), and power down again!!!
