  Had a quick look, using libdrm seems a bit excessive for what we want to do here. The current /sys digging also doesn't exactly fill me with joy though :(

As it turns out the /proc/dri stuff was supposedly removed here https://github.com/torvalds/linux/commit/cb6458f97b53d7f73043206c18014b3ca63ac345 making this code entirely irrelevant since kernel 3.12.
Any objections to removing it altogether?
