I heard a couple people playing with this, and I have confirmed their findings. Minecraft does not run w/ IcedTea/OpenJDK. If you wish to play under linux, you will need sun/oracle's jdk.
This is the error you receive when you try to run it

eep, I was wrong. Turns out I did not have permission to do opengl with my user (video group in /etc/groups). Ignore me.
Still running it through wine here (due to errors I am informed are vaguely something to do with propriety graphics drivers)
