    That doesn't look like an error to me, just an informational message of some kind of fallback. Do you have any problems?

    This isn't an error, we only use 32bits addressing in radeon so maximum address is 0xFFFFFFFF. Here 0xFFFFFFFF-0xD0000000 doesn't have enough space to fit the AGP gart space so we have to put a AGP at different address in GPU address space than in CPU address space. This is harmless but for years we have been worried about bad use of gpu and we always tried to put AGP gart space at same address in GPU address space than in CPU address space so any wrong setup would still hit the gart. IMHO we should move to same setup as fglrx ie starting GPU address space a 0x0 but that's another discussion.
