Hmmm, that's interesting. I found some info on "tainted" or "not tainted" kernels, but it seems like you should get the modules output. You might try as a regular user instead of root, and you might try after a fresh reboot to see if it makes any difference. Root and regular user showed the same for me.
You can get the same information using cat /proc/modules but it may add some junk at the end, and the formatting is not as clean. This command cat /proc/modules | awk '{ print $1, $2, $3, $4 }' | column -t produces a nicer output. Copy and paste it into your terminal.
Here is what they both look like (just showing the last 10 lines after piping output to 'tail').
