Works for me too on a Dell Studio 1749.
Steps:
1. Create new file /etc/modprobe.d/blacklist-suspend.conf with the following two lines:
blacklist firewire_core blacklist firewire_ohci
2. Run: sudo update-initramfs -u
3. Reboot and check that the modules were not loaded by running: lsmod | grep firewire
4. Suspend the machine and bring it back up.
5. Hibernate the machine and bring it back up.
Both suspend and hibernate work now.
