Got some "bumblebee z11 success" her too! Thanks, Zheng and Heikki.

Some of the main issues that required fixing in my configuration for this 
VPCZ11Z9E:

1) Xorg: "no screens found"
[XORG] (EE) intel(0): Failed to claim DRM device.
[XORG] (EE) Screen(s) found, but none have a usable configuration.
[XORG] (EE) no screens found(EE)
To fix, I need this in my device section of /etc/bumblebee/xorg.conf.nvidia:
BusID          "PCI:1@0:0:0"

2) No enabled displays
"(WW) NVIDIA(0): Unable to get display device for DPI computation."
I had to explicitly specify my displays to be connected and enabled by adding 
to /etc/bumblebee/xorg.conf.nvidia under screen section:
Option      "UseDisplayDevice"      "DFP-2, DFP-0"
Option      "ConnectedMonitor"  "DFP-2, DFP-0"
DFP-2 is my sony-lcd, DFP-0 is HDMI.

3) "(WW) NVIDIA(0): Unable to get display device DFP-0's EDID; cannot compute 
DPI from DFP-0's EDID."
Sadly, even though reading EDID works fine elsewhere, the nvidia driver doesn't 
seem to be able to do so. So the customedid lines are required:
Option         "CustomEDID" "DFP-2:sonylcd.edid;DFP-0:mytv.edid"


The remaining issues are specific to setting up the HDMI port, which is 
actually the main reason I turned to Bumblebee as I couldn't get any image 
through HDMI with the basic nvidia  driver package without Bumblebee.

Remaining problems to fight:

1) HDMI EDID
For the laptop display, specifying the EDID file manually is ok since it never 
changes. The HDMI port edid is more problematic; not only would I need to 
change the script but I'd also have to obtain the EDID for whatever display I 
might want to use on the go.

2) display suspend
Another big problem seems to be the external display shutting down after a 
while, and I cannot get it back on without rebooting the Bumblebee X server.

3) Acceleration for internal LCD when HDMI also enabled
I don't know whether Bumblebee is designed to work with two display devices. 
If I have both DFP-2 and DFP-0 (HDMI) enabled, drawing to X display ":8" draws 
to the external display. Running OpenGL application with optirun with ":0" 
seems to try to draw to the internal LCD but fails to do so with error:
