yes. i386 would be correct. You should see a lot of library (.so) files in that directory, including libjava.so
One last point. Mincraft requires ridiculously memory requirements on Linux to run well. It runs adequately on my daughters elderly single core Athlon box with 2gb of memory, but really struggled on my amd64 triple core Ubuntu based box with the same memory and trying to run the Minecraft client, Bukkit server and Eclipse (to develop plugins) would make the whole system grind to a halt. Upping the memory to 4gb stopped it continually bashing the swap file and made things much smoother.
