I tried using wine today and I encountered two problems. (1) Everything was rendered upside-down. It was really hard to click on things because you still had to click where they should be on screen, only they were vertically mirrored. (2) My z-buffer was messed up. So the furthest objects were rendered in front of closer objects. All models had eyes popping out of their heads, teeth in front of their mouths. Water boxes were jumping at me and if I stopped moving the skybox is all I could see.
Some screenshots for fun, these are on KingMorts RA server:

As far as Cedega, I haven't tried it out but people are saying it doesn't run eq anymore... The woes of enjoying a game for too long, we're all supposed to be playing WoW you know.
If anyone has success running eq on Linux or Unix, please spill your juicy secrets.
