Can someone post a config file for the 280x? I honestly don't know how to configure an X11 miner, I am new to mining X11 and it seems a little different then mining scrypt.
Also, does it matter what kernel I use in the X11 multipool?
the answers has been given already above, but to give you a straight answer: you will need the darkcoin kernel of sgminer
the default sgminer works perfect for Liberty multipool
If you have questions you can also leave them in our multipool support forum:
