Any benefit on using the kernel on Tahiti cards (280x) at all?
Maybe - I haven't tried all settings - if you want to try something new, try it out. You'll want to change your settings, though; I basically implemented a lookup gap of 2.

Maybe you could hand the compile job over to someone you know so we would all know it was safe :-)
