I do not understand what you mean, could you explain this again? Nouveau
is blacklisted on my system. 
Important first question: I thought that the new kernel does not need an
older kernel for switching anymore...?
If I just use the new kernel and set the switch to speed the led goes to
speed just before GDM starts. If I boot with in the stamina setting the
led for stamina switches on just before GDM starts.

This does not work, since I have no working glx module ("extension GLX
missing").

There must be something wrong with my system configuration. I just
started in Speed mode a few times. X loads the i915 driver (lsmod shows
i915 loaded), although I blacklisted that, my xorg.conf specifies
"nvidia". X also tries to load the NVIDIA glx module. Excerpt from my
Xorg.0.log in Speed mode:

In Stamina mode X still loads the i915 driver, which seems correct. The
libglx.so it tries to load is from NVIDIA, so I removed the link. Now X
cannot find the glx driver, since there is nog glx driver for the i915
(or should there be?):

I can currently only use my Z11 without problems if I boot the 2.6.31-20
kernel with the NVIDIA proprietary drivers and an xorg.conf that
specifies to use the nvidia driver.

I hope this helpt in making the kernel work for everybody.
I'd gladly do some more testing.
