if gdm crashes, try e.g. kdm/xdm/...

So something tries to load the first fitting driver for some piece of
hardware discovered. Duplicating the aliases that are already built into
the module (well both modules in your test case) gives them a higher
precendence.

If you drop the aliases again and instead create
/etc/modules-load.d/nvidia.conf with the content "nvidia" to have to
module autoloaded on boot - does this work?

Have you tried to use the driver without manual Xorg configuration? I.e.
tested that starting X with nvidia driver automatically works with
glx-alternative-nvidia 0.5.90. (Requires the nvidia kernel module to be
loaded before X is started)
