With ACPI the control of Power Management is given into the hands of the OS. It means you can suspend machines which have a BIOS that doesn't support suspend to disk or suspend to ram as the OS emulates the process. This could be the case with your notebook. I have a hp omnibook xe4400 and a similar behaviour. I didn't manage to find out if my machine has the ability to suspend to disk from bios yet. Anyway, swsusp (software suspend) works like a charm. Have a look at http://sourceforge.net/projects/swsusp for the kernel patches and the scripts to suspend your notebook.
