Latest driver from AMD.com and the latest AMD APP SDK, latest guiminer, latest gpu-z, latest afterburner.

Will show some screenshots soon!
...and you can't mine with a single 6990 core (i.e. any one of the four cores)?

Also are you attempting solo mining or pooled?
I'm rather good with Linux.  If you're having problems with your mining rig I'll help you out remotely for 0.05.  You can also propose a flat-rate for some particular task.  PM me for details.
Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

Right now Im just trying to get one 6990 to work properly (just one card in the mobo) and I can see just one core in guiminer if CrossfireX option es disabled in CCC, and I can mine ok but as i said just one core... If I enable CrossfireX option in CCC, I see both cores in guiminer but one core work ok and the second give "Verification failed, check hardware!" error.

Also in AfterBurner I see just one core with the right info, and the other core appears like no info... core speed, etc.

Download LinuxCoin and put it on a thumb drive or CD to see if you're able to run it on all the cores.  You should see two devices for each 6990 card.

Is an OpenCL problem! Cant fix it but Im using AOCLBF with phoenix and is ok... anyways when I use both cores (As I said Im using only one card right now 6990) gpu usage goes like 60% in both cores is weird... using one core give 99%


Edit:

FINALLY FIXED !! Special thanks to "Departure" !!
