I just tested this and it works fine. This just combines the two scripts in my last post into one. Now I need to figure out how to use devilspie with this and it will be perfect.
Code:
#!/bin/sh
#Start EQ in a separate X session
X :3 -ac &
cd "/home/insert-your-user-here/.wine/drive_c/Program Files/Sony/EverQuest"
sleep 2
DISPLAY=:3 taskset -c 0 wine eqgame.exe patchme
