I have already PMed AMDMATT, But I want this BUG to be known.
7990 Quadfire is not working after driver 7.9.3. Only 3 GPUS can be enabled and the 4th one shows, but can't be enabled via radeon software. I verified this via GPUZ.
Anyone who has a 7990 Quadfire please test... I bet thats like zero users.... who cares maybe this also impacts the 1 other user who has a 295x2 quadfire!
Anyway please test and fix this issue. I like the fact that my esoteric system was supported via software and still running right.
System specs for those who will ask.

2x ASUS ARES 2 quadfire
ASUS rampage IV formula (latest bios)
