Hi!

  
Anyhow, I did some hacks into pci_device_suspend() getting it to 
suspend devices without a driver. Combined with my escalation patch 
in pci_set_power_state() all devices on the machine now enters D2 or 
D3 depending on device capabilities. My laptop still cannot enter the 
suspend state so there is still something missing... Are there any 
more areas of power management in linux that aren't quite up to spec.?
    

You forgot to say if you are trying to suspend to ram or to disk.

RAM. It was in the beginning of the thread...
