Until, in several years, pointers get larger than 64bit ;-p

Actually, I still didn't get the point why such simple things
have to be ioctl()s (which are unportable and and local-only
by design). Why not just using plain file operations ?

(eg. getting the version info could be as simple as someting like:
`cat /dev/dri/version`)
