Yesterday I upgraded the original hdd with a brand new one with 80 GB and reinstalled ubuntu from scratch. Then I upgraded and hibernation worked, even without the resume=/dev/hda5 and with the splash screen enabled. The only problem I have encountered is when I use vga=791 (or 792): in this case the computer hibernates, but when I turn it on it goes through a normal startup, not a dis-hibernation.
