If only they offered the Tyan's pre-configured with four 7990's instead of Teslas which are 3-4 times as expensive, my company might have gone for it.
I followed your BIOS settings but to no avail, the box is exhibiting the same behavior.
Instead of using a backported kernel, I was going to just install quantal or raring so I didn't have to deal with backporting xorg. If that doesn't work, I was going to try CentOS 6.4, since the box officially supports RHEL 6.4, according to their website.
What bothers me is that the box will not consistently post with all four 7990's, which means this is probably not an OS issue. Sometimes it does, but when I shutdown or reboot it just hangs after it starts most of the time. I have tried moving the cards to different slots and any one of the four 7990's will work by itself, and even any combination of three. When I connect the fourth card, everything turns on and spins up, but that is it. If I connect the monitor to any of the 7990's with the fourth card in, it will just stay blank and the monitor will report that there is no video signal. If I connect to the VGA/USB port on the back, I get the status code of 0xAD, which is the "Ready To Boot event," according to the manual.
Can I ask what you did to get your Tyan boxes up and running?
