Thanks for the suggestions Seth, I tested and here's what I got: 1- I tried increasing vmalloc (went as far up as 256M). What I see then is the system freezing when I do pm-suspend. It doesn't go into suspension, but the keyboard and mouse stop responding, only remaining option is to reboot.
2- Same behavior when using the 64-bit kernel (in fact, a whole new 64-bit installation), it freezes, becomes unresponsive and I have to reboot. 3- I then installed the proprietary nvidia drivers: [ 18.486] (II) NVIDIA(0): Creating default Display subsection in Screen section [ 19.144] (II) NVIDIA(0): NVIDIA GPU GeForce 9400M G (C79) at PCI:3:0:0 (GPU-0) [ 19.168] (II) NVIDIA(0): Assigned Display Device: DFP-0 [ 19.168] (II) NVIDIA(0): Validated modes: [ 19.168] (II) NVIDIA(0): ""nvidia-auto-select"" With these proprietary drivers, the system successfully suspends, and comes back from restore with some garbling on the screen, what I did was maximizing the terminal (F11) and that basically "sweeps" the display and it's usable, although the background itself turns white. So it's better and possibly usable, it might need some work done, but more importantly, confirms your diagnosis about nouveau keeping the system from successfully suspending. Let me know if more testing is needed.
