Same here with my P35 and only with the radeon driver, if I switch to fglrx it works (some time system hangs but thats a other problem). With the radeon only display didn't comeback again after suspend to ram. I can make a reboot with the shutdown button or over the console (without seeing anything). So system is runing fine only no display.
