"vbetool vbemode get" prints "3", and there are no segfaults. Using vbemode doesn't really make anything better, though. Using it inside X causes the video to stay black after resume. Using it on a framebuffer console produces better results than without vbemode, but the framebuffer is still messed up. It's more readable because there's not per-row corruption...instead, parts of the screen get translated around. I figured out another thing about this laptop - s2ram success has nothing to do with whether it's running a 32 or 64 bit kernel. The only thing that makes any difference (once the video issue is handled) is whether or not the ide driver is in use. I thought 32-bit was special because booting into knoppix made s2ram work - but really the only difference is no use of /dev/hda. If I run 'cat /dev/hda > /dev/null' while suspending, I get a lockup during resume just like on 64-bit. Conversely, if I make a custom initrd that boots a 64-bit kernel but doesn't load any ide module, and do the suspend/resume in the initrd before mounting root, I can s2ram repeatedly with no problem. Oddly, in the 32-bit knoppix case, the use of the cdrom doesn't seem to be a problem. The lockups only happen when the hard drive gets involved.
