Hi,

Suspend and hibernation didn't work for me with 2.6.37-vaioz (as reported by others), so I sticked with 2.6.36. 
I can't comment or complain about battery life, I just felt the laptop was quite hotter with the newer kernels, so I checked actual power consumption. And Watts don't lie. :)

Cheers,
-- Daniel
