Never forget - google is your friend :-) Especially groups.google.com
From alt.os.linux.mandrake:
Exactly the same problems here. Then I used the rpm on the December Linux Format DVD version (media/drivers/) subdirectory.
nvidia-kernel-2.6.8.1-10mdk-6111-1mdk.i586.rpm
instant success.
There is one dependency. Can't rember whether it was dkms-nvidia-6111-1mdk.i586.rpm or nvidia-6111-3mdk.i586.rpm
either way both are in the /media/drivers/subdirectory so urpmi nvidia-kernel-2.6.8.1-10mdk-6111-1mdk.i586.rpm will sort it
