And how did I achieve this?
By switching slots! Instead of having my 5870 in the low-order slot (and the 9270 in the high) I swapped them. (Given the sizes of these mothers, that ain't easy.) The 9270 and the 5870 are BOTH RECOGNIZED!! The best I could do the other way was to get an "Unknown" graphics board for the 9270.
Guys, your drivers leave a LOT to be desired when they can't find your premiere graphics card because of its POSITION.
System: i7 920 oc'd to 3.07GHz, 12GB RAM, Radeon 5870/Firestream 9270 graphics cards, SuSE Linux 11.2 kernel 188.8.131.52-0.2, installed ati-stream-sdk-v2.01, ati-driver-installer-10-3. I even got my acmlg1.0 working!!
