It seems that a lot of GPU problems revolve around specific versions of drivers. Though AMD has their own support structure, you can often learn from information reported by others who fold.
I see my GPU in the white list but, I get an error (On client "local" 127.0.0.1 No more GPUs) when trying to add it via the configure/slots (It doesn't add it automatically). I wouldn't have thought it would be in there with how old it is. But, I think it's in there.
Please note that in your log, this is present:
02:33:48: GPU 0: UNSUPPORTED: Radeon RV250 [Mobility FireGL 9000]
Unfortunately, your GPU isn't supported by F@H. The Whitelist does contain information that blacklists any unsupported GPUs to avoid any potential issues. Thus, it is more of a greylist than either a whitelist or a blacklist.

The Radeon 9000 is in the GPUs.txt file, but the file is both a white list and a blacklist. It is not supported for folding. The oldest Radeon GPU's supported are from the HD 5000 series. The last projects that could use older cards ran out some time ago. AMD-ATI dropped support for the older GPU programming language and went to OpenCL a couple years ago. F@H made an announcement in the blog at the time that current projects would be finished up, future GPU folding projects for AMD-ATI cards would use OpenCL.

(side note, while HD 4000 series cards "support" OCL, their version does not work the same as current driver version, depending on firmware some of the earliest release HD 5000 series cards act like HD 4000 series and won't fold _x16 or _x17)
