Yes, please: nvidia taints the kernel - so flame at your will - but
this is a more general question regarding module loading:

If I load the nvidia kernel module like this:

% modprobe nvidia NVreg_Mobile=2  NVreg_SoftEDIDs=0

and start kdm afterwards, it works as in 2.4 -- I get a two screen
setup with one screen on my laptop TFT and one on my external TFT
screen.

If I use this /etc/modules.conf:

... snip ...
### update-modules: start processing /etc/modutils/nvidia-kernel
alias /dev/nvidia* nvidia
alias char-major-195 nvidia

### update-modules: end processing /etc/modutils/nvidia-kernel

### update-modules: start processing /etc/modutils/nvidia-options
options nvidia NVreg_Mobile=2 NVreg_SoftEDIDs=0

### update-modules: end processing /etc/modutils/nvidia-options
... snap ...

the X11 will barf upon start -- but the module will be loaded. From
Xfree.0.log:

...
