You need to put it onto the kernel cmdline, the modprobe configs take it in the
format

options <module-name> <options>

Note the lack of a . in between. So if you want to put it into the modprobe
files you need a new line with

option drm debug=0xe

Most distros also require you to rebuild the initramfs images, since gfx module
get loaded fairly early. Hence it's quicker for a quick debug run to add in to
the kernel cmdline (with the . included).
