It doesn't change anything, but I have a couple of questions/observations that could possibly point us in the right direction: - Is there a possibility that some userspace program is locking up the video, keyboard, and mouse? I tried stopping all the services that I could (including X11) and although the video froze (display powered up, frozen cursor as before), the keyboard was responsive to a capslock press. I haven't had time to isolate the particular service that was causing that behavior. - I tried compiling my kernel without framebuffer (vesafb-tng) or splash (Gentoo's fbsplash) support, and the behavior is the same as before except the cursor blinks. Are framebuffer drivers an issue for suspend-to-RAM? Perhaps trying the intelfb driver would give better results? I should also point out that I've tried removing all modules that I could and suspending. This hasn't helped either. I'm going to try installing Fedora Core on this laptop and see if some particular configuration element of my Gentoo installation is causing lockups. Thanks for all your help.
