When I load the fglrx ati proprietary driver (11.1) for the 5450 card, then=
 I
get throughputs of about 2GB/s in both directions.=20

Running the same test in same environment on the HD5970=20
with the gallium drivers and kernel mode setting and pcie_gen2 activation, i
get about the same figures as above.
With fglrx for 5970, then 5970 only performs well in CPU->GPU with about 2G=
B/s
and only 0.5GB/s in GPU->CPU direction=20

I have included the test and configuration output for both cases (fglrx and
radeon) and also code for the testprogram might you want to reproduce this
case.
