Try suspend-and-resume without X. Also, try it on one of the more modern laptops - even *with* X. Basically, the kernel wants to be able to do what X does, because it means that when it works, it works _so_ much better than doing it in X. So getting it working is definitely worth it. That said, before you do anything else, try if suspend-to-RAM works. That's the primary goal for this code anyway, and if it works that gives a good hint. Suspend-to-disk is fundamentally different, and it's entirely possible that for the suspend-to-disk case we should just say "screw trying to suspend/resume graphics", since you'll have the BIOS resuming text-mode anyway, and there are no performance or debugging advantages.
