The synaptics touchpad on my EeePC 701 dies on hibernation.  2.6.30 was
fine, and it doesn't happen on suspend to ram either.  There are no
obvious error messages, but maybe this boot message is relevant:

Platform driver 'i8042' needs updating, please use dev_pm_ops

    
        

Similar on s2disk, HP/Compaq notebook. Try reload psmouse module. I
reported it, but nobody answer.
  
      

That works, thanks.
    

Alan, Maciej, can you both try the patch at
http://patchwork.kernel.org/patch/34075/, please?

I've been having the same issue (laptop touchpad not working after resume).
Your patch seams to fix the problem. I no longer have to reload the 
psmouse module after resume.
