Hi,
   I'm able to successfully hibernate while using nouveau with kernel version
2.6.35 (and before) but unable to hibernate in 2.6.36 (and after up to
2.6.39-rc$YESTERDAY).
   I am not using X.  From the console I test whether hibernate is possible
using "pm-hibernate".
   I've bisected this and located a range of possible commits which changed
this behavior.  
last known good: d17f395cdcec39033a481f96d75e8b3d3c41d43a
first known bad: 816544b21b020bdb9dcb9a5003fe3e1f109e8698
   Between these commits the kernel would not compile.


   This is the nVidia card in the machine.
02:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400]
(rev b2) (prog-if 00 [VGA controller])
        Subsystem: nVidia Corporation Device 0054
        Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 11
        Memory at dc000000 (32-bit, non-prefetchable) [size=16M]
        Memory at d0000000 (32-bit, prefetchable) [size=128M]
        [virtual] Expansion ROM at dd000000 [disabled] [size=64K]
        Capabilities: [60] Power Management version 2
        Capabilities: [44] AGP version 2.0

Let me know if I can provide more info or test patches!

Thanks,  Chad.
