sorry to hear that man...i hate when my computer goes down... (how DO you run seam on linux? do you have to use wine?)
Yeah, steam runs ok in Wine. But just OK. You have to tweak things, like use older versions of DirectX. I ran steam in Wine for a while, but could never quite get my FPS up where they needed to be. They ran consistently 20-30 FPS slower than in windows XP.
Hope you get it fixed soon.My computer is back and ready for play some source games.
