This conflict is expected, as the package is marked as Multiarch:
foreign , since it installs the sources to /usr/src/<nvidia-version>
and there would be a conflict.

Now that is quite strange, I've never seen that error:
/dev/dri/card0: failed to set DRM interface version 1.4: Inappropriate ioctl for device
[ 260.044] (--) PCI:*(0:1:0:0) 10de:1401:1043:8520 rev 161, Mem @ 0xf6000000/16777216, 0xe0000000/268435456, 0xf0000000/33554432, I/O @ 0x0000e000/128, BIOS @ 0x????????/524288
The only thing that comes up in Google is bug #764639. I don't suppose
the blacklisting of nouveau is missing? Having the output of reportbug
Also trying manually from a TTY to load the module and start X might
give more clues.
But I have to stress that this is a bit uncharted territory, I have
never tried a setup with different archs for kernel and userspace, so I
am not sure I'll be able to help. I can try :-)
