YES!
Installing from kernel-ppa: linux-image-2.6.25-1-generic linux-ubuntu-modules-2.6.25-1-generic FIXED it!
It now hibernates correctly and resumes reliably!
The only problem I have is that the bootsplash breaks the screen (it usually turns black), so I had to remove "splash" from the kernel line.
[Another thing: Ubuntu completely non-informative while suspending to disk; it only prints "drm_sysfs_suspend" during the whole operation.]
