Why would modinfo say a module is not found when it appears with lsmod

I have noticed several cases where, if I use lsmod to find a module and then use modinfo for that module, it comes out with a ERROR: Module not found message. For example with the Nvidia module (When using the proprietary drivers).

So in what cases would a module appear on lsmod but give an ERROR like the one I mentioned above with modinfo.

It's being aliased. In my example (similar to yours perhaps):

lsmod | grep nvidia

nvidia               9171294  51



modinfo nvidia

ERROR: modinfo: could not find module nvidia



modprobe --resolve-alias nvidia

nvidia_current



grep -r nvidia /etc/modprobe.d/

/etc/modprobe.d/nvidia-graphics-drivers.conf:alias nvidia nvidia_current



modinfo nvidia_current

filename:       /lib/modules/3.7.5-030705-generic/updates/dkms/nvidia_current.ko

alias:          char-major-195-*

version:        313.09

[...]

Above should speak for itself, doesn't it?
