It is unclear to me when reading your comments whether this is a problem with any graphics driver or the kernel. Can you please boot with the "text" boot parameter, and log in to the console and run "pm-suspend" ?
A possible related upstream report would be http://bugs.freedesktop.org/show_bug.cgi?id=19581 for radeon.
Also, today the linux-image-generic 2.6.28-11 is released in Jaunty and contains some drm updates. Please try it out.
