I've been looking carefully at test patterns to figure out what is going on. If (1,1) (2,1) (3,1) (4,1) (5,1) (6,1) (7,1) (8,1) (1,2) (2,2) (3,2) (4,2) (5,2) (6,2) (7,2) (8,2) (1,3) (2,3) (3,3) (4,3) (5,3) (6,3) (7,3) (8,3) (1,4) (2,4) (3,4) (4,4) (5,4) (6,4) (7,4) (8,4) (1,5) (2,5) (3,5) (4,5) (5,5) (6,5) (7,5) (8,5) (1,6) (2,6) (3,6) (4,6) (5,6) (6,6) (7,6) (8,6) is what should be displayed, I'm getting instead (1,1) (2,1) (3,1) black (4,1) (5,1) (6,1) black (7,1) (8,1) (1,2) black (2,2) (3,2) (4,2) black (5,2) (6,2) (7,2) black (8,2) (1,3) (2,3) black (3,3) (4,3) (5,3) black (6,3) (7,3) (8,3) black (1,4) (2,4) (3,4) black (4,4) (5,4) (6,4) black (7,4) (8,4) (1,5) black (2,5) (3,5) (4,5) black i.e., a black pixel is inserted every thee pixels. However, it's not just a garbled display, the acceleration (I think) is also bogus. When I tried setting a solid colour using echo -e '\e[47m', instead of the above display, I got (1,1) (2,1) (3,1) black (4,1) black black black black black (1,2) black (2,2) (3,2) (4,2) black black black black black black (1,3) (2,3) black (3,3) (4,3) black black black black black black (1,4) (2,4) (3,4) black (4,4) black black black black black (1,5) black (2,5) (3,5) (4,5) black i.e., in addition to a black pixel being inserted every three pixels, one of the halves of the "source" image is black. And in the X virtual console, the cursor is ungarbled. Two other thing of note is that virtual consoles 2-6 are garbled after only some boots. (vc7, the X server console, is always garbled). And output below the as-displayed bottom of a garbled virtual console prevents me from switching to a different vc. (I get "radeonfb FIFO Timeout !"/"radeonfb Idle Timeout !" on the serial line).
