The device tree has this to say:

Devices:device-tree:bandit:ohare
#address-cells = [00000001 = 1]
#size-cells = [00000001 = 1]
AAPL,address = [f3000000 = -218103808]
assigned-addresses
class-code = [00ff0000 = 16711680]
device-id = [00000007 = 7]
device_type = "dbdma"
devsel-speed = [00000001 = 1]
max-latency = [00000000 = 0]
min-grant = [00000000 = 0]
model = "AAPL,343S0172"
name = "ohare"
ranges
reg
revision-id = [00000001 = 1]
vendor-id = [0000106b = 4203]

ATI 264VT2

Maybe the host bridge also does byte swapping on the frame buffer??
