Will not suspend on toshiba nb305

[Adam Smith]

Previously I had suspend working fine. On top of the base Ubuntu 10.04 install I needed to add nomodeset nohz=off highres=off to my boot kernel parameters to avoid failed suspend / very slow bootup (15mins). This is discussed on this thread https://bugs.launchpad.net/ubuntu/+source/linux/+bug/508516/

Since installing the 10.10 release candidate however, I have found that suspend does not work. It closes all the GUIs and goes to a black screen, but does not shut down and continues using full power.
