Same problem with me (dell d505, intel 801 card).
I have tried to chance several options inside /etc/defaults/acpi-support, as discussed in
https://bugs.launchpad.net/ubuntu/+bug/38915/comments/61
No success. So, I decided to test if my system could hibernate from console, using /etc/acpi/hibernate.sh from command line. This gave me some freezes as well and a clue: acpi and kernel.
The only think that it is working at this moment: adding acpi=off inside menu.lst.
I can not hybernate anymore but system is working after logout.
So, problem seems to be related to kernel+acpi+video.
I can help in debugging if someone say me what to do (files, logs, etc).
