Status of my VPC Z1: all good except power management

 

Hi,

I've recently received my VPCZ1 (VPCZ13A7E to be precise). So far, I
only:
 * installed a stock 64bits Ubuntu 10.10
 * booted with nomodeset to install Adams'
linux-image-2.6.36-0-vaioz_2.6.36-0.1_amd64.deb
 * and that's it.
No special boot options in grub, unmodified BIOS (R3030C3), switch on
stamina position, and that gives me a 1600x900 resolution, wifi, sound,
mic and webcam, all working right away. Powertop reports a power usage
of 13W (with medium luminosity and mostly idle Wifi connection). (I
forgot to mention that Fn-F2 to F6 to control brightness and volume
worked too). So I feel quite spoiled already :) Thanks to everyone that,
in a way or another, got us that far.

I do have a problem though with power management. As reported on some
blogs, resuming from suspend-to-ram leaves a black screen, and so far
only plugging an external monitoring and toggling between console and X
could light up the internal panel (playing with xrandr didn't help). I
haven't tried hibernation much, but the last time I tried it seemingly
froze during restoration. 

Unfortunately, the 2.6.37-6 kernel is clearly worse with that regard,
with resuming from suspend that just boots (BIOS logo, then grub) and
hibernation that basically reboots (the computer doesn't even halt, it
just reboots).

Are there grub options, pm scripts, kernels I should try? Extra
information I should provide?

Best,
-- Daniel
