The current code in hal for dm detection is really ugly imho. I think the right
way (tm) is to push the kernel people to put some more info in sysfs for dm
devices. (I'm currently playing with the code to see how i can do that).

And obviously i'm interested in your sesame code :), so lemme know if the starts
of it are available somewhere..
