Try commenting out the line below:
#export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100
I did it a month ago.
But I found solution: miner starts if I run it from tty console (I've to do it locally, not over ssh) and it crashes if I trying to run it any other way, so I can't use autorun after server reboot.
