Is it Possible To Have Disqus AND Facebook Comments?

This might seem like a bizarre question,as you probably wonder why i want that.Well most people don’t use the Connect buttons associated with Disqus & also I think it would allow the greater intergration with my Facebook page that i need.
You can do it on Tumblr,my patner’s blog has both,go look to see what i mean.(That is Anthagio’s Themerazzi theme that I have played around with BTW)
I was just wondering because one comment plugin on WP would usually cancel the other out,am I wrong!!??
