Supposed problems abound for the Open-Source AMD Fusion platform
If you have been thinking about picking up a motherboard with one of AMD's new Fusion E-350 "Zacate" APUs to use with the open-source Fusion driver, you may want to hold off for a bit or be forewarned that it could be a bumpy ride.
UPDATE: It turns out that the Ubuntu mainline kernels are missing the Fusion firmware. However, when dropping in the upstream PALM and SUMO firmware, the graphics still fail; black screen with the cursor and it's soft locked-up but there is still remote access. The new dmesg.
UPDATE 2: A fix is available and should be in the Linux 2.6.38 final kernel.
