Hi all,

i can confirm, that this works on my Z21WN/B !!!!

Thanks a lot Klaus, how did you find out ?

This is quite a step forward, as we now _dont_ need an Xp cd /install
anymore.

Still i am not sure what exactly does the proper initialisation of the
nvidia card. I did the following things:

Boot with acpi_osi="!Windows 2006", without nvidia driver installed and
with eva & matzes module in speed_stamina=3 mode. i reloaded it in
intel/stamina mode
I quit X, killed gdm and installed the nvidia driver and modified the
xorg.conf. A modprobe nvidia gave, that the card was not properly
initialised - a known result.
I did an  "sudo halt" and at the next start, the nvidia card was
working.

Now the question is, can we make this work, so it recognises the Speed -
Stamina switch ?

Eva, Matze: Does the boot option give you a hint how to properly
initialise the card ?

it would be great, if we somehow managed to make it work only with a
script and a reboot. So that the card is chosen on startup depending on
the switch setting. Thats the second best option after on the fly
switching, and actually as acceptable for me. Especially as Xorg ppl
might take some years, until they are getting the infrastructure set up
to handle this correctly ..

Ciao

Julius
