can't get more than two GPUs to work

[ragequit]

Using Suse 12.3
catalyst 13.4
oclHashcat 1.0

4x Asus DirectCUII 7970

Code:

aticonfig --list-adapters
* 0. 01:00.0 AMD Radeon HD 7900 Series
  1. 02:00.0 AMD Radeon HD 7900 Series
  2. 03:00.0 AMD Radeon HD 7900 Series
  3. 04:00.0 AMD Radeon HD 7900 Series

* - Default adapter

trouble seems to center around card 0 and 1...
If I do a --adapter=2,3 during initial config all is well, I get 2 devices working when I use hashcat.

--adapter=all, hashcat freezes unless I comment out the

Code:

BusID "PCI:x:0:0"

lines in xorg.conf. Then I just get one device.

additionally, X doesn't load unless I comment out the BusID lines....

Any ideas???
