Try going through some of these:
That is the built in video of your board according to :
Your graphics use the ATI Hybrid CrossFireX™ technology, so you might be
running into this issue:
[support graphics card hot switch]
Note comment 1:
OT (but also important): And also on the amd/ati side there are
problems. Many laptops have two graphics chips inside (hybrid
crossfire), but x cannot start, not even with vesa. We need to do
something about this. Thanks.

See if there are any bios settings in the graphics that you can change.

Not that I know of. My guess is the crossfire/graphics issue above, so
I'd search those links and see if you pin down a workaround.
