Hmm, RC1 works flawlessly. I tried RC2 but it's bugged bad? I thought it might have been incompatible with sdk 2.1 (wont hash at all), so I tried 2.6. It has a different error, but it hashes slow compared to 2.6, and I refuse to use 2.6 and be forced to use high memory clocks and waste power.
heres my config file.
[general]
verbose = True
backend = http://1CxcPP8FVktppy4PHTYJKnZFqQeyZ3jArb:x@mining.eligius.st:8337
[cl:1:1]
kernel = phatk2
AGGRESSION = 14
VECTORS = true
BFI_INT = true
WORKSIZE = 256
[web]
disable = true
heres the error with 2.1 sdk (cl:1:1)

heres the error with 2.6 sdk (cl:0:0)

back to using rc1 until bug is fixed.
