This is the only thing I've noticed that an icon does: http://i.imgur.com/UbxCfCb.png
(firefox > greasemonkey > userscripts list)
Thanks. Icon?
Wrote my own xkcd userscript. Tried to make my own regex include url, couldn't do it, so I used yours. Hope you don't mind.
I also made an icon for my script. Modified it slightly for you. You can use it for your script if you like.

Add these lines to your script if you wanna use it:
// @icon http://i.imgur.com/1kN9qms.png
// @icon64 http://i.imgur.com/98DeEZD.png
Imgur is good for hosting, no need to rehost the images.
Cheers. No hard feelings if you don't use my icon attempt.
